Chapter IX:
The Korean War and its Aftermath
It is apparent that the United
States is required to increase its military strength and preparedness
not only to deal with the aggression in Korea but also to increase our
common defense, with other free nations, against further aggression.
President Harry S. Truman 1
In June 1950, when a Soviet
trained and armed North Korean army attacked South Korea, the Cold War
turned hot. The U.S. Army was forced to adopt emergency expedients
during the first months of the war, but the maintenance of a
significant military sustaining base after World War II, a response to
Soviet-American tensions, allowed the nation to mobilize more quickly
and easily than in the past. Within a year and a half the number of
Army combat divisions on active duty went from ten to twenty. The
Army, reacting to changing political, strategic, and operational
requirements worldwide, for the first time in its history reassessed
its reserve forces during a major war. Nevertheless, the end of the
fighting in Korea brought new reductions, which resulted in fewer Army
divisions by the end of the decade than during the war.
The invasion of South Korea on
25 June 1950 exposed a hollow Army. Divisions in Japan were completing
a reorganization that reflected greatly reduced manning and equipment
levels. The 1st Cavalry Division and the 7th, 24th, and 25th Infantry
Divisions all lacked reconnaissance, military police, and replacement
companies, medical detachments, and bands. Their infantry regiments
were each short one battalion and the tank company, and the 105mm.
howitzer battalions had only two firing batteries. Only one company or
battery was filled in the tank and antiaircraft artillery battalions.
Tank companies were equipped with the M24 light tank because the Far
East Command had feared that heavier tanks would damage Japanese roads
and bridges. The one exception was the 25th Infantry Division, which
fielded a black regimental combat team built around the 24th Infantry.
In that team the infantry regiment and the field artillery battalion
had all their elements, but at reduced levels. The authorized
strengths of the divisions ranged between 12,500 and 13,650 officers
and enlisted men.2
[239]
Although the divisions fell
well below war levels, President Harry S. Truman responded to the
United Nations resolution to stop aggression in South Korea by
ordering troops to Korea on 30 June. The next day Task Force Smith,
elements of the 24th Infantry Division, the closest to Korea at Kobura,
Japan, deployed to Suwon, South Korea, by air. The rest of the
division quickly followed by sea. Shortly after the 24th's departure,
the Far East Command brought the 25th Infantry Division and the 1st
Cavalry Division to some semblance of effective fighting strength by
stripping the 7th Infantry Division. By the end of July both divisions
had joined in the fight, with the almost totally gutted 7th Division
remaining in Japan.3
As the three understrength
divisions fought in Korea, the Army Staff set about to bring them to
full strength, along with the 7th Infantry Division in Japan.
Personnel were involuntarily extended, and the length of their
overseas tours was increased. Other commands were cannibalized for
units, personnel, and equipment. Particularly scarce in the Far East
Command were tanks and antiaircraft artillery. Because all the
divisional tank and antiaircraft artillery battalions there had been
reduced to a company or battery, replacement units had to come from
the United States. With the divisions in Korea taking heavy casualties
and the replacement system on the verge of bankruptcy, several months
elapsed before the units neared war levels.4
Heavy losses and the amount of
time required for units and personnel to reach the Orient resulted in
an agreement on 15 August between the Far East Command and the South
Korean government for the temporary assignment of Korean nationals to
U.S. Army units. Under the Korean Augmentation to the United States
Army (KATUSA) program, approximately 8,600 Koreans were to serve in
each American division as soldiers. Various barriers-language,
cultural differences, inadequate training, and unfamiliarity with Army
organization, weapons, and tactics-hindered the program from achieving
its goal. A few months after the plan's inception, the command
curtailed it because of improvements in the replacement system and the
desire to concentrate on rebuilding the Republic of Korea Army.
Although U.S. divisions continued to receive some Korean recruits, no
division received the 8,600 initially envisaged.5
With United Nations troops
being overwhelmed in South Korea, General Douglas MacArthur, the
United Nations Forces commander, requested immediate reinforcements
from the United States. In July he asked for the 2d Infantry Division,
stationed at Fort Lewis; a regimental combat team from the 82d
Airborne Division at Fort Bragg; and some smaller units. Army Chief of
Staff General J. Lawton Collins refused to send a regimental combat
team from the 82d Airborne Division, preferring to keep the division
intact for other contingencies. Instead, he favored dispatching a team
from the 11th Airborne Division at Fort Campbell built around the
187th Airborne Infantry. The Joint Chiefs of Staff obtained President
Truman's approval for the moves on 9 July, but many units in the
United States had to be stripped to fill the 2d Division before it
could deploy.
[240]
2d Infantry Division elements move through a mountain pass south
of Wonju, Korea, 1951.
Elements of the 2d arrived in
Korea on 31 July, and the division entered combat in late August. The
187th did not arrive until October.6
The arrival of the 2d Infantry
Division in Korea allowed Lt. Gen. Walton H. Walker, commanding the
Eighth Army there, to withdraw the 24th Infantry Division from combat
along the Naktong River. Due to the heavy losses sustained by the
division, Walker decided to transfer all personnel and equipment from
the 34th Infantry and the 63d Field Artillery Battalion to other units
in the division, replacing them with the 5th Regimental Combat Team
(organized around the 5th Infantry), which had recently arrived from
Hawaii. With the infusion, the division was ready for combat again by
the end of August. Subsequently the 34th Infantry and 63d Field
Artillery Battalion returned to Japan, where they were reorganized to
train replacements.7
In August 1950 MacArthur
planned an amphibious assault at Inchon, Korea, that would include the
7th Infantry Division, the only U.S. Army division left in Japan. To
replace it in his reserve, he requested deployment of the 3d Infantry
Division, the last Regular Army infantry division in the United
States. After much debate in Washington, Truman sanctioned its
deployment. Since a large portion of its personnel and equipment had
been withdrawn earli-
[241]
er to meet other demands in
Korea, the 3d Division had fewer than 5,000 men. To address the
personnel problem, the division commander reassigned the personnel
from one of its regimental combat teams and one general support field
artillery battalion elsewhere in the division. At the same time, the
Army Staff assigned two field artillery battalions and attached the
65th Infantry, the Puerto Rican regiment, to the division. The 3d
Infantry Division arrived in Japan on 15 September, except for the
65th Infantry, which had moved directly to Korea from Camp Losey,
Puerto Rico. In Japan the division received a Korean augmentation and
began to train for combat. As elements of the 3d arrived in Japan,
elements of the 7th Infantry Division landed at Inchon. Following the
Chinese intervention in the war during the fall of 1950, the 3d
Infantry Division also moved to Korea where the 65th Infantry joined
it.8
The attachment of the 65th
Infantry to the 3d Infantry Division marked a departure in the Army's
segregation policies. In the past native Puerto Ricans were assigned
exclusively to Puerto Rican units. In September 1951 the only units in
which Puerto Ricans could serve outside the Caribbean area were
elements of the 65th Regimental Combat Team in Korea. However, since
more Puerto Ricans had entered the Army than were needed for these
segregated Spanish-speaking units, the Army removed all restrictions
on the assignments of Puerto Ricans who spoke English.9
The first few months of the
war the Army relied on stopgap measures to field its six undermanned
divisions in Korea but was still able to evolve a strategy for
conducting the war. Under MacArthur, a strategy of attrition was
quickly replaced by a strategy of annihilation. When the Chinese
entered the war in the fall of 1950 the United Nations reverted to an
attrition strategy, but one which depended on firepower rather than
manpower. No major reinforcements would be provided to the forces in
Korea. Although limited manpower mobilization in the United States
solved many personnel problems in the Far East Command, divisions
continued to lack trained infantry and artillery troops. After the
United Nations spring counteroffensive, which ended on 8 July 1951,
negotiations began for an armistice, with the number of Army divisions
in Korea remaining fixed at six until the summer of 1953.10
To field the divisions
destined for Korea, the Army stripped the General Reserve of its
resources. After the summer of 1950 its divisional units consisted of
only the understrength 2d Armored Division, the partially organized
11th Airborne Division, and, closest to its wartime authorized
strength, the 82d Airborne Division. The reserve had to be quickly
rebuilt for other contingencies, particularly for Western Europe,
where many national leaders feared a major challenge from the Soviet
Union. In July defense officials began discussing the means for
enlarging the Army, but many months passed before they
[242]
decided upon a program. In the
meantime, the Army expanded piecemeal. Secretary of Defense Louis
Johnson approved the activation of another infantry division on 14
July 1950, but it was not until October that the 4th Infantry
Division, which had been serving as a training division at Fort Ord,
moved to Fort Benning to be reorganized as a combat unit. The Army
Staff expected the division to be trained by the late spring of 1951.11
Because it would have taken
too much time to organize new Regular Army divisions and Class B
Organized Reserve Corps divisions (officers and enlisted cadre), the
Army's leadership decided to recommend bringing some understrength
National Guard divisions into federal service. On 10 August the
president approved inducting four Guard infantry divisions. To
accommodate them, the Army reactivated four World War II camps, and
early in September the 28th (Pennsylvania), 40th (California), 43d
(Connecticut, Rhode Island, and Vermont), and 45th (Oklahoma) Infantry
Divisions entered active federal service. Army Field Forces and the
Army Staff selected those units because of their geographic
distribution, the status of their equipment, and their strength, which
ranged from 8,000 to 9,500 officers and enlisted men each. The Army
Staff immediately began working to bring the divisions up to their
full table of organization and equipment strength.12
Initially individual
reservists recalled to active duty filled Regular and Guard divisions,
but to maintain them and other divisions, as well as organize new
units, the Army Staff relied on volunteers and draftees who were
schooled in existing or reactivated training centers. To operate the
centers, Army Field Forces activated five Regular Army divisions, the
8th Infantry at Fort Jackson, South Carolina; the 101st Airborne at
Camp Breckinridge, Kentucky; the 5th Armored at Camp Chaffee,
Arkansas; the 6th Armored at Fort Leonard Wood, Missouri; and the 7th
Armored at Camp Roberts, California, between August and November 1950.
The 6th Infantry Division was also reactivated to replace the 4th at
Fort Ord.13
The Chinese intervention in
the fall of 1950 stimulated broader mobilization measures. After
considerable debate, President Truman declared a national emergency,
which required additional military forces to meet the Soviet threat in
Europe as well as to fight the war in Korea. The mobilization plan
called for eighteen combat divisions to be on active duty by June
1952. To obtain the additional divisions, the president approved the
induction of the National Guard's 31st (Alabama and Mississippi) and
47th (Minnesota and North Dakota) Infantry Divisions into federal
service in January 1951. These were reorganized under reduced tables
that called for approximately 14,500 officers and enlisted men. For
the eighteenth division, the Army reactivated the Regular Army's 1st
Armored Division in March. This last unit improved the balance in the
active force among infantry, armored, and airborne divisions, which
stood at 2 armored, 2 airborne, and 14 infantry.14
In the fall of 1951 the Joint
Chiefs of Staff reevaluated the mobilization program and set a new
goal of twenty-one active duty combat divisions by 31 December 1955.

Infantry Divisions were
brought into federal service in early 1952, but the twenty-first
division was not federalized or activated because of budgetary limitations. Thus the Korean War and the Cold War mobilization peaked
at twenty divisions (Table
21).15
Personnel policies for manning
divisions during the Korean War differed from those used in World Wars
I and II. Prior to 1951, when soldiers went overseas to fight, their
tour was usually for the duration of the war. With far-flung
commitments throughout Europe and Asia, Army leaders adopted a
personnel rotation policy during the second year of the Korean War.
They hoped such a system would avoid alienating the general public and
maintain the morale of the soldiers themselves. To accommodate the
additional personnel needed to implement the rotation, the training
base was further expanded in the spring of 1951. The 5th Infantry
Division was activated at Indiantown Gap Military Reservation,
Pennsylvania, increasing the number of training divisions to ten, the
maximum number during the Korean War (Table 22). General
Reserve divisions were also tasked to train recruits.16
By April 1951 the Army was
able to provide additional forces to improve the security of Japan,
where no divisional reserve had existed since the Chinese inter-

vention in the Korean War. The
40th and 45th Infantry Divisions moved to Japan, where they completed
their training. Congress insisted, however, that the National Guard
divisions have an opportunity to fight, and in the winter of 1951-52
the 40th and 45th Divisions replaced the 1st Cavalry and 24th
Infantry Divisions in Korea. The method of exchange revived a
technique that had been developed during World War II. Ships that
carried the 40th and 45th Infantry Divisions to Korea brought the 1st
Cavalry Division and 24th Infantry Division back to Japan. The

units swapped all heavy
equipment and supplies while the men carried only their personal arms
and equipment with them. Thus the units experienced only a limited
decline in combat efficiency. The two seasoned divisions returned to
Japan to serve as a reserve. Until July 1953 the 2d, 3d, 7th, 25th,
40th, and 45th Infantry Divisions carried the fight in Korea. During
the waning days of the conflict, immediately before the armistice on
25 July, the 24th Infantry Division returned to Korea as a rear area
force to bolster the security of prisoner-of-war camps. 17
In 1952 Congress authorized
what were in effect eight more divisions for the National Guard to
replace the units in federal service. These organizations gave some
areas of the country military forces where none had existed since
units were federalized two years earlier for the Korean War. Under the
new law the federal government could retain National Guard units
(exclusive of personnel) for five years, but the states could organize
replacements for the units in federal service. The new local units
were to have the same designations as the units in federal service,
with the additional identification NGUS (National Guard of the United
States). Furthermore, the legislation required that when the Guard
units in federal service were returned to the states, they were to be
consolidated with their sister organizations. States began organizing
NGUS units in 1952, and by the end of the Korean War on 23 July 1953,
six out of the eight Guard divisions in federal service had local
counterparts. Of the remaining two, the 37th Infantry Division (NGUS)
received federal recognition on 15 January 1954, but the 44th never
had an NGUS counterpart. The governor of Illinois, as an economy move,
declined to organize it and requested the state's troop allotment be
amended to delete the 44th Infantry Division. The division was removed
from the force when it was released from federal service in December
1954.18
In addition to fighting the
war in Korea in the early 1950s, the nation committed forces to the
North Atlantic Treaty Organization (NATO). Since 1947 only the 1st Infantry Division had been stationed in Europe, but with the
establishment of NATO President Truman announced a substantial
increase in forces there. Between May and November 1951 the 2d Armored
Division and the 4th, 28th,
[246]

and 43d Infantry Divisions
joined the 1st Infantry Division in Germany. The commitment of these
forces and similar actions by the NATO partners demonstrated a new
reliance on collective security to deter aggression. 19
During the Korean War the Army
modified some aspects of its divisional organizations, but the basic
triangular structures adopted during World War II and revised in the
immediate postwar period for infantry, armored, and airborne divisions
remained intact. In 1952 a divisional ordnance battalion replaced the
ordnance company, which increased self-sufficiency in each type of
division. The trend in most organizations, however, was to save
personnel and increase firepower. Chief of Staff Collins estimated
that the changes in the infantry division enhanced its firepower by 68
percent compared to its World War II counterpart with only a 20
percent increase in personnel.20
Firepower in the infantry
regiment was increased through a series of changes. A 105-mm.
recoilless rifle found a place within the regiment, as did the more
powerful 3.5-inch "bazooka," a rocket fired from a shoulder
position. In the first engagements of the Korean War, the 2.36-inch
bazooka had proved inadequate against the Soviet T-34 tanks supplied
to the North Koreans. To meet the Far East Command's requirement for
an improved antitank weapon, 3.5-inch rocket launchers were rushed to
the theater. On 20 July 1950 elements of the 24th Infantry Division
used
[247]
3.5-inch rocket launcher in action against the North Koreans
them to knock out several
Russian-built tanks, and thereafter the weapon received wide use.
Infantry used new models of the 81-mm. and 4.2-inch mortars, and the
number of automatic rifles was increased in the regiment.21
Improved aircraft technology
provided all three types of divisions with new resources. The
helicopter, boasting both vertical lift and hover capability, became a
practical tactical and transport asset, playing a key role in supply
and medical evacuation in Korea. Infantry and airborne divisions were
authorized sixteen traditional fixed-wing aircraft and ten
helicopters, while each armored division fielded eighteen aircraft and
ten helicopters. The debate again surfaced as to whether all
divisional aviation should be located in one unit since they usually
used the same airfield. No separate aviation unit won approval, and
technically the aircraft remained dispersed to the various units
throughout the divisions. Divisions in combat, however, centralized
their aircraft under divisional aviation officers who organized
provisional aviation companies.22
The Army made more significant
changes in the armored division. Although large armored formations
were considered unsuitable for the rugged terrain in Korea, the Army
still faced a massive Soviet armored threat in Europe. In response,
the armored division fielded the first new family of tanks since World
War II. The M103 (T43) tank armed with a 120-mm. gun was authorized
for the heavy tank battalion. Weighing about sixty tons, it was the
largest and most powerful American combat vehicle adopted to date. The
new medium tank, the M47, had an improved fire control system and a
high-velocity 90-mm. gun, which enhanced its lethality, but it did not
become available in any quantity until 1953. For the reconnaissance

Bulldog) destined for the 705th Tank Battalion, 102d Infantry Division
squadron the tables provided
for the new M41 light tank, nicknamed the "Walker Bulldog"
for General
Walker, who had been killed in a jeep accident in Korea.
In a11, the armored division fielded 343 tanks.23
The divisions deployed in
Korea, Japan, and Germany usually adopted changes shortly after they
were
announced, in contrast to those in the United States. The latter,
except for the 82d Airborne Division, served in a training capacity,
mostly providing replacements for the overseas forces. As noted,
training centers failed to meet the demand for replacements, but the
political decision to limit mobilization precluded expanding the
existing training centers or opening others, forcing the Army to use
combat divisions to perform that function.24
The Korean War brought about a
major social change that touched all units throughout the Army. The
Army had maintained all-black units since the Civil War, but military
efficiency tests showed that blacks fought and performed better in
integrated units than in segregated ones. Also, post-World War II
social attitudes increased the demand for integration. In 1948
President Truman had directed desegregation of the armed forces, but
the Army was slow, as were the other services, to respond. By May
1951, however, 61 percent of the line infantry companies in Korea had
both white and black soldiers because little consideration was given
to replacement by race. On 1 July of that year the Army authorized the
new Far East commander, General Matthew B. Ridgway (Truman had
relieved MacArthur the previous April) to integrate all units under
his control, except for the 40th and 45th Infantry Divisions. These
units, which had recently arrived from the United States, were exempt
from the order because they were National Guard organizations. The
Army feared political repercussions from the states if their units
were racially mixed. Nevertheless, despite the initial hesitation, the
40th and 45th were integrated shortly after they entered combat in
Korea.25
The Far East Command usually
integrated units through normal administrative processes. For example,
the 3d Battalion, 9th Infantry, and the 3d Battalion, 15th Infantry,
elements of the 2d and 3d Infantry Divisions that had been filled with
black soldiers, were desegregated by simply reassigning them. The 25th
Infantry Division had the 24th Infantry, the only all-black regiment
in the Regular
[249]
Army, and Ridgway approved
inactivating the regiment to disassociate all divisional elements with
segregation. The Army Staff transferred the 14th Infantry, less its
personnel and equipment, from the United States to the Far East
Command, and on 1 August 1951 the regiment replaced the 24th in the
division. Most of the 24th's black soldiers were dispersed throughout
the command, while white soldiers to fill the 14th were drawn from the
34th Infantry in Japan. Units in the other regional commands
integrated soon thereafter.26
Hostilities ended in Korea on
23 July 1953 when the United Nations and North Korea signed an
armistice, but demobilization, like mobilization, did not follow a
preplanned course. A threat still hung over Korea, and the defense of
Western Europe remained of paramount concern. The size of the Army
depended on the new president, Dwight D. Eisenhower, inaugurated in
January 1953, who was committed to reducing military expenditures.
Between 1 July 1953 and 1 July 1956, the Congress, at the president's
request, cut the active Army from 1.5 to 1 million men, a reduction
that required major adjustments in divisional forces.27
By that time the annual load
in the training centers had stabilized at a lower peacetime level, and
the Army Staff had turned its attention to improving the General
Reserve, particularly as a reenforcement force for Europe. In October
1953 the staff designated the 1st Armored Division and 44th Infantry
Division as 30-day reinforcement units for NATO and named the 82d
Airborne Division as the Western Hemisphere's contingency force. To
bring these and other divisions in the General Reserve up to war
levels, the 5th Infantry, 7th Armored, and 101st Airborne Divisions,
which had been operating training centers, were inactivated and their
personnel reassigned. The training center operated by the 10th
Infantry Division was also closed, and a new mission was planned for
the division.28
In December 1953 Eisenhower,
who had hesitated to reduce forces in Korea because of the precarious
armistice, announced that two of the seven U.S. Army divisions there
were to return home, a step permitted by improved capabilities of the
South Korean Army. United States Army Forces, Far East, selected the
40th and 45th Infantry Divisions for return to the United States, and
they departed Korea in the spring of 1954 with only a token personnel
complement. Shortly thereafter the divisions were released from active
federal service and reverted to state control. Concerned about the
effects of demobilization because of events in Southeast Asia (the
French were on the verge of withdrawing from that area), Secretary of
Defense Charles E. Wilson suspended further reductions in the Far East
Command on 7 April 1954.29
Although the Army could retain
National Guard designations for five years, Secretary Wilson decided
to release the 28th, 31st, 37th, and 43d Infantry Divisions to state
control in June 1954. This decision was primarily an adminis-

trative action and did not
affect the actual number of combat or training divisions in active
service. In Europe the 9th and 5th Infantry Divisions replaced the
28th and 43d Infantry Divisions, while the 8th and 10th Infantry
Divisions in the United States replaced the 31st and 37th at Fort
Carson and Fort Riley. The 69th Infantry Division and the 101st
Airborne Division were reactivated to fill the gaps left by the 5th
and 9th in the training base.30
By the summer of 1954 the
Mutual Defense Treaty with the Republic of Korea and the expansion of
its army to twenty divisions permitted additional American reductions
in Korea and allowed the Department of Defense to release all reserve
units from active duty. In October the 25th Infantry Division with its
personnel and equipment moved from Korea to Hawaii, where it became
part of the Pacific area reserve. Shortly thereafter the 2d and 3d
Infantry Divisions, reduced to near zero strength in Korea, replaced
the National Guard 44th and 47th Infantry Divisions at Forts Lewis and
Benning. The Guard divisions returned to state control, thus ending
the involvement of the reserve divisions in the Korean War. When those
divisions left federal service, only their designations reverted to
the states since the guardsmen themselves had been released earlier.
The states reorganized the units, except for the 44th, which Illinois
did not want, by using the NGUS divisions as the nuclei, as planned.31
After many revisions of the
blueprints for a residual force in Korea, the Department of Defense
instructed the services to plan for three divisions, one Army, one
Marine, and one United Nations, plus combat support and combat service
support units to remain there. In December 1954 Secretary Wilson
decided that the Marine unit would return to the United States,
leaving two Army divisions in Korea. As a result, the 24th Infantry
Division, in the midst of moving to Japan, reversed its course and
rejoined the 7th Infantry Division in Korea.32
[251]
To improve the balance within
Regular Army divisional forces after the Korean War, General Ridgway,
who had become Army Chief of Staff in 1953, decided to revise the
ratios among infantry, armored, and airborne units. In June 1954 the
Fourth Army activated the 4th Armored Division, the first division to
be equipped with the new M48 90-mm. tank. Ridgway planned to organize
another armored division, raising the Regular Army total to four, but
tank production lagged, preventing its formation until 1955. The 3d
Armored Division was then converted from a training to a combat unit.33
Although total Army strength
declined and the reserves were released, the Army remained committed
to an active force of twenty divisions. The Department of Defense,
therefore, authorized the activation of the 23d and 71st Infantry
Divisions. Those units, dubbed "Wilson Divisions" after
Secretary of Defense Wilson, who approved their activation while
cutting the strength of the Army, made use of existing regimental
combat teams. The 23d Infantry Division, the former Americal Division
of World War II fame, controlled units stationed in the Canal Zone,
Puerto Rico, and the southeastern United States from its headquarters
at Fort Amador, Panama Canal Zone. The 71st, with its headquarters at
Fort Richardson, Alaska, included units in Alaska and the northwestern
United States. Because of their scattered divisional elements, the
Army Staff labeled the divisions "static units," indicating
that they were not capable of early deployment.34
With further cuts on the
horizon for the Regular Army, the Army Staff had to economize on
manpower if it was to maintain twenty divisions. A review of all
divisional tables of organization resulted in slightly smaller
divisions. For example, without a change in structure, the infantry
division dropped from 18,212 men of all ranks to 17,452. In addition,
the tables provided for a reduced peacetime strength division, with
some 2,700 fewer men for each division in the General Reserve. Before
its divisions were sent into combat, they would, of course, need
sufficient time and personnel to be brought to war strength as
required for sustained operations. The lessons of Task Force Smith and
the deployment of other units to Korea in the summer of 1950 thus
appeared to be already lost. General Reserve divisions adopted the new
tables in the summer of 1955. In addition, because of the Army's
severe manpower shortages divisions in Europe were also reorganized
under the reduced tables that same summer, and the tables were applied
to the 25th Infantry Division, posted at Schofield Barracks, the
following year.35
Besides looking at the
organizational tables for possible personnel cuts, the Army examined
the individual replacement system. The system traditionally required
the Army to maintain a large manpower overhead as a substantial
percentage of its soldiers were always in transit. Lt. Gen. John E.
Dahlquist, Chief of Army Field Forces, and Maj. Gen. Robert N. Young,
the Army Staff's Deputy Chief of Staff for Personnel (G-1), believed
that a unit replacement system would be more economical, improve
esprit de corps, and provide more efficient units. In response, the
Army Staff developed the GYROSCOPE program, which paired a division in
the United States with an overseas division. Personnel from the paired
[252]
divisions were to exchange
places every three years. In addition, the divisions in the United
States were to conduct basic and advanced individual training, cutting
the training base and providing each soldier with a home throughout
most of his career. It also theoretically made it possible to replace
an entire division if it were destroyed in a nuclear attack.36
Beginning in 1955 fourteen
divisions participated in the GYROSCOPE program (Table 23). To meet
the changing needs of the Army, however, some deviation occurred
during the duration of the program. For example, the l1th Airborne
Division from Fort Campbell replaced the 5th Infantry Division in
Germany in 1956, but the 5th's new station was Fort Ord, a former
training center. Several benefits resulted: the European command
received an airborne division, a unit it had wanted for some time; the
U.S. Continental Army Command (CONARC), successor to the Army Field
Forces, gained a post, Fort Campbell, and equipment to test a new
divisional structure for the airborne division; and the number of
divisions remained unchanged.37
As the divisions rotated, the
U.S. Army, Europe, and Seventh Army closely monitored their activities
and readiness to determine the effect of the moves on the units. They
found that divisional combat efficiency declined for a number of weeks
before and after rotation, and Lt. Gen. Bruce C. Clarke, Seventh Army
commander, recommended limiting GYROSCOPE to units smaller than
divisions. In 1958 the last divisional exchange took place when the 3d
Infantry Division from Fort Benning replaced the 10th Infantry
Division. Thereafter the program involved only smaller-size units. On
I September 1959 the Army terminated GYROSCOPE, following the
recommendations of General Clyde D. Eddleman, Commander, U.S. Army,
Europe, who believed that other replacement systems worked better with
less disruption. GYROSCOPE helped to sustain morale, but the scheme
did not save money or improve combat readiness.38

With divisions in the
GYROSCOPE program conducting individual training, the Department of
the Army reduced the number of training centers. By 1 July 1955 only
seven major training centers remained, of which five were operated by
divisions. The continued use of divisional names for the centers,
however, was being questioned. Lt. Gen. Walter L. Weibir, the G-1,
wanted to change the centers' names to reflect their missions more
accurately. For some time the divisional designations had confused the
general public, government officials, and the trainees. In the spring
of 1956 the Army thus inactivated the 6th and 69th Infantry Divisions
and 5th and 6th Armored Divisions and reassigned the 101st Airborne
Division as a test unit. Branch replacement centers replaced the
training divisions. For example, the organization at Fort Chaffee,
Arkansas, became the U.S. Army Training Center, Field Artillery.39
The savings that resulted from
the revised tables of organization, modifications in the replacement
system, and a reduction in the training base did not equal the
required cuts in Army strength. The Army was therefore unable to
maintain twenty Regular Army divisions. Further reductions required
the commanders of United States Army, Caribbean, and Sixth Army to
inactivate the 23d and 71st Infantry Divisions in 1956. Some of their
elements, however, continued to serve in the active force.40
The structure of the reserve
components came under close scrutiny during the Korean War. By then
military leaders had decided the large undermanned force of fifty-two
divisions developed after World War 11 was unrealistic. On 24 October
1950 the chief of staff directed a committee to reevaluate the reserve
structure and develop plans to meet both limited and major
mobilizations. Six months later, before the decision to mobilize 20
divisions due to the Korean War, the committee reported that the Army
needed 18 divisions on active duty-12 Regular Army and 6 National
Guard-and 33 reserve divisions to back them up. The latter divisions
fell into two categories for mobilization, an early ready force of 9
divisions from the National Guard and a late ready force of 24
divisions with 12 from the Guard and 12 from the Organized Reserve
Corps. The units in the National Guard were to be maintained at 100
percent officer and 50 percent enlisted strength, while those in the
Organized Reserve Corps were to have 100 percent of their officers but
only an enlisted cadre. The committee decided that the remaining
thirteen Organized Reserve Corps divisions were unnecessary and
recommended their immediate inactivation.41
During the summer and fall of
1951 the six army commanders in the United States, staff agencies, and
the Section V Committee, created after World War I for the reserve
components to have a voice in their affairs, evaluated the plan. The
army commanders urged that all divisions in the Organized Reserve
Corps be infantry divisions because they believed that the reserves
could not adequately
[254]
support armored and airborne
training. They thought thirteen, rather than twelve, reserve divisions
should be maintained to provide a better geographic distribution of
the units. The Section V Committee opposed the reduction of the
Organized Reserve Corps from twenty-five to thirteen divisions because
it feared unfavorable publicity, particularly with the nation at war.
On 20 December the Vice Chief of Staff, General John E. Hull, delayed
reduction in the number of Reserve Corps divisions until 31 December
1952 but directed the reorganization and redesignation of airborne and
armored divisions as infantry as soon as practicable. In March 1952
the 80th, 84th, 100th, and 108th Airborne Divisions were reorganized
and redesignated as infantry divisions, and the 63d, 70th, and 75th
Infantry Divisions replaced the 13th, 21st, and 22d Armored Divisions.
The Army made no other divisional changes in the reserve troop basis
at that time.42
Along with the reorganization
of the Organized Reserve Corps divisions, the Army published new
regulations formalizing a "Ready Reserve" concept. Under the
new rules the Ready Reserve comprised Early and Late Ready Forces,
categories which replaced the old Class A, B, and C units. The Early
Ready Force was to have 110 percent officer and 100 percent enlisted
strength, while the Late Ready Force, which included all Organized
Reserve Corps divisions, was to have 100 percent officer and 5 percent
enlisted strength. In July 1952 Congress passed new legislation that
redesignated the Organized Reserve Corps as the Army Reserve and gave
legal status to the concept of the Ready Reserve.43
Before the dust had settled on
the reforms, the Army realized that it had failed to improve unit
manning or meet reasonable mobilization requirements. In the fall of
1952 Army leaders thus proposed that the personnel from the thirteen
inactivated Army Reserve divisions be assigned to strengthen the
remaining twelve divisions. A new reserve troop basis resulted, this
time calling for 37 divisions, 27 in the National Guard and 10 in the
Army Reserve. To keep the unneeded fifteen Army Reserve divisions
active, they were to be reorganized as training divisions to staff
training centers upon mobilization or man maneuver area commands for
training troops. The continental army commanders implemented the new
Army Reserve troop basis in 1955 piecemeal. They reorganized, without
approved tables of organization, the 70th, 76th, 78th, 80th, 84th,
85th, 89th, 91st, 95th, 98th, 100th, and 108th Infantry Divisions as
cadre for replacement training centers and organized the 75th
"Maneuver Area Commands" using the resources of the 75th
Infantry Division. Two years later the 75th Infantry Division was
inactivated along with 87th Infantry Division. Assets of the 87th were
used to organize a maneuver area command; thus one unneeded division
remained in the troop basis.44
To prepare for challenges in
Western Europe, the new troop basis authorized the conversion of four
National Guard infantry divisions to armored divisions. New York,
California, Georgia, and Florida agreed to convert the 27th, 40th, and
48th Infantry Divisions. For the fourth armored division, the Army
planned to use the slot temporarily occupied by the 44th Infantry
Division, which Illinois no longer wanted. Eventually Tennessee and
North Carolina, which shared the 30th Infantry
[255]
Division, each agreed to
maintain a division; Tennessee organized the 30th Armored Division,
while North Carolina organized the 30th Infantry Division.45
In 1955 Congress again
legislated measures to improve the reserves. Among the amendments to
the 1952 law was a provision that allowed young men eighteen and a
half years old to enlist in the Army Reserve for eight years. Not less
than three and not more than six months of that obligation was to be
spent on active duty for basic training. The law also provided that
reservists who did not perform satisfactorily after basic training
might be ordered, without their consent, to active duty not to exceed
forty-five days. Although the Army Reserve hoped these provisions
would help to meet manning problems, the measure failed. Most young
men were uninterested in military service, and for the few who were
the active Army lacked the resources to provide basic training and the
National Guard proved more attractive than the Army Reserve.46
At the beginning of 1957 the
Army thus had 56 combat divisions and 12 training divisions. Of these,
the Regular Army fielded 18 combat divisions, many not fully manned;
the National Guard 27; and the Army Reserve 11. Of the 56 divisions, 3
were airborne, 10 were armored, and the remainder were infantry.
Between 1950 and 1957 Army
divisions fought a war in Korea and deterred the Soviet challenge in
Western Europe. At the height of the Korean War the active Army had
eight divisions in the Far East, five in Germany, and a seven division
General Reserve in the United States. Divisions retained their World
War II structure with modifications while gaining additional
firepower. As the United States assumed leadership of the Western
democracies, a ready force, backed by fully manned and equipped
reserves, took on added significance. Nevertheless, the Regular Army,
National Guard, and Army Reserve divisions all suffered from a lack of
personnel. After the Korean War budgetary constraints exacerbated the
manning conditions, while the general reliance of the Eisenhower
administration on nuclear deterrence put the fiscal emphasis on
weapons systems rather than on the combat divisions.
