An Overview of the Demobilisation of US Armed Forces after World War II


The Demobilization of United States armed forces after the Second World War began with the defeat of Germany in May 1945 and continued through 1946.

The United States had more than 12 million men and women in the armed forces at the end of World War II, of whom 7.6 million were stationed abroad. The American public demanded a rapid demobilisation and soldiers protested the slowness of the process. Military personnel were returned to the United States in Operation Magic Carpet. By 30 June 1947, the number of active duty soldiers, sailors, Marines, and airmen in the armed forces had been reduced to 1,566,000.

Total Personnel in Uniform

In 1945 as the defeat of Germany and Japan neared, US military personnel numbered 12,209,238 divided among the services as follows:

BranchNumber of Personnel
Army Air Force2,400,000
Coast Guard85,783

This total represented wartime expansion of the US military from the 334,000 it had been in 1939. 100,000 men were being drafted per month to replace soldiers in the army who were killed, wounded, and injured or who were discharged for medical problems.

Note: “Uniformed military personnel” will often be referred to collectively as “soldiers” in this article, unless the context requires more specification.


As early as mid-1943, the United States Army had recognised that, once victory was achieved, bringing the troops home would be a priority. US soldiers were scattered across 55 theatres of war worldwide. Army Chief of Staff General George Marshall established committees to address the logistical problem. Eventually, organisation of the operation was given to the War Shipping Administration (WSA). It established and coordinated Operation Magic Carpet.

Germany Surrenders

On 10 May 1945, two days after the unconditional surrender of Germany to the allies on V-E Day, the War Department announced a point system for the demobilisation and discharge of Army and Army Air Force enlisted personnel. The point system, called the Adjusted Service Rating Score, had the objective of achieving equity in the demobilisation. Soldiers were given one point for each month of military service and one additional point was given for each month of overseas service. Each battle star or decoration earned a soldier 5 points. Soldiers were awarded 12 points per dependent child up to a maximum of three children. A total of 85 points was needed for eligibility. Soldiers who had earned that number of points were to be demobilised as soon as transport back to the United States was available. Women in the Women’s Army Corps (WACs) were eligible for demobilisation with 44 points.

The War Department initially projected demobilising 2 million soldiers in the 12 months following the victory in Europe:

  • 50% of this total were in Europe;
  • 33% in the Pacific; and
  • 17% had already returned to the US after an overseas assignment.

The Navy, including the Marine Corps, postponed demobilisation until the defeat of Japan. The great majority of Navy and Marine Corps personnel were located in the Pacific region. Some soldiers in designated specialties were declared ineligible for demobilisation despite having accumulated 85 points. Officers were not initially included in the point system for demobilisation.

Initial Demobilisation in Europe

On V-E day, 3 million American military personnel were in Europe. Additional replacement soldiers were in the pipeline to be assigned to Europe although overall force levels had been declining for several months as the war wound down. Army and Army Air Force units in Europe were classified into four categories for the purpose of occupation, redeployment, or demobilisation.

  • Category I consisted of units to remain in Europe. The occupying force for Germany would consist of eight divisions and a total occupying force of 337,000 personnel to be reduced further in June 1946.
  • Category II consisted of units to be re-deployed to the Pacific. About one million soldiers were slated to be sent to the Pacific, including 13 infantry and 2 armoured divisions. 400,000 soldiers were to go directly from Europe to the Pacific to arrive between September 1945 and January 1946; another 400,000 were to undergo eight weeks of retraining in the United States and continue to the Pacific to arrive by April 1946. About 200,000 Air Force personnel were to go to the Pacific, either from Europe or the United States.
  • Category III units were to be reorganized and retrained before being reclassified into Category I or II.
  • Category IV units were to be returned to the US to be inactivated or disbanded and personnel discharged. Category IV units consisted of soldiers who qualified for discharge under the point system. The total number of soldiers in Europe to be discharged was planned to be 2.25 million between the end of the war in Europe and December 1946.

As departures of soldiers from Europe was to be by units, a massive reshuffling of personnel took place to get soldiers eligible for demobilisation into units designated for return to the US and deactivation. Turnover of personnel in one typical unit, the 28th Infantry Division, was 20 percent for enlisted men in one week and 46 percent for officers in 40 days. This impacted efficiency and unit cohesion.

The demobilization proceeded rapidly. Assembly areas to accommodate 310,000 soldiers were established in France. The soldiers lived in tent cities while waiting for transport back to the United States. In May 1945, 90,000 soldiers were repatriated, but others would have to wait months for transport as the war in the Pacific had first priority for ships and aircraft. Elaborate schemes of education and travel were attempted by the military to maintain morale during the waiting period. Upon arrival in the US, soldiers would undergo final out-processing at a number of designated military bases.

Defeat of Japan

When Japan surrendered on 02 September 1945, the demand for rapid demobilization from soldiers, their families, and Congress became unstoppable and all previous plans became moot. Conscription was reduced to 50,000 men per month, less than the military’s requirements for replacements. Soldiers, sailors, and marines in the Pacific became eligible for demobilisation. The points required for demobilisation were reduced several times, reaching 50 points on 19 December 1945. Ten aircraft carriers, 26 cruisers, and six battleships were converted into troopships to bring soldiers home from Europe and the Pacific. Racial segregation on the troop ships created a problem. In December 1945, the Navy barred 123 African-American soldiers from sailing home because they could “not be segregated” on a troop ship.

The War Department promised that all servicemen eligible for demobilisation from Europe would be in the US by February 1946 and from the Pacific by June 1946. One million men were discharged from the military in December 1945. Every congressman was “under constant and terrific pressure from servicemen and their families” to discharge soldiers more rapidly.

Soldiers Demand Faster Demobilisation

The rapid demobilisation of American servicemen threatened to create a shortage of manpower for the responsibilities of occupying Germany, Austria, and Japan. On 04 January 1946, the War Department backtracked on its previous promises of early demobilization and announced that 1.55 million eligible servicemen would be demobilised and discharged over a six-month period rather than in three months as previously announced. This announcement generated immediate protests from soldiers around the world. Four thousand soldiers in Manila had demonstrated against the cancellation of a repatriation ship on Christmas 1945. On 06 January, 20,000 marched on army headquarters. The protests spread worldwide, involving tens of thousands of soldiers in Guam, Japan, France, Germany, Austria, India, Korea, the United States, and England – where 500 disgruntled soldiers confronted Eleanor Roosevelt. Although a few soldiers were arrested, most commanders took a tolerant approach to the demonstrations. Communist involvement in the demonstrations was alleged, but unproven.

In Washington, Army Chief of Staff General Eisenhower ordered an investigation of the Manila demonstration and concluded that the main cause was “acute homesickness” and recommended that “no mass disciplinary action be taken” against the demonstrators. The military sped up demobilisation by liberalising the point system once again to further speed up demobilisation, although Eisenhower banned any further demonstrations and threatened court-martials for participants. The military also took steps to make service abroad more appealing. Basic training for new soldiers was shortened from 17 to 8 weeks. The army offered free travel to families of servicemen if the soldier agreed to remain overseas for two years. Occupation troops in Europe were offered a 17-day European tour for the nominal price of between 25 and 35 dollars (roughly $350 to $490 in 2021).


Rapid demobilisation, in the view of military planners, left the US military understaffed to accomplish its responsibilities. In addition, the number of conscripts being drafted into the army was smaller than those needed to replace demobilised soldiers. The unpopular draft was terminated on 31 March 1947, and the US military became an all-volunteer force until new legislation authorising a draft was adopted in 1948.

The number of personnel in the US military between mid-1945 and mid-1947 was reduced almost 90%, from more than 12 million to about 1.5 million.

BranchNumber of Personnel (as at 30 June 1947)
Army Air Force306,000

The rapid demobilization of the US military after World War II, in the words of one scholar, reduced the army “to a state of near impotency, weakened the prestige of our national policy, and endangered the security of the Nation.” Although the combat capability of the US certainly declined because of the demobilisation, another assessment of the US military in Germany concluded that the army still had defensive capability and the “ability to perform occupational duties, to control the German population, and to suppress local uprisings”. The occupation of Japan proved also to be relatively unchallenging. A new (and highly unpopular) Selective Service Act of 1948 restored conscription as a response to challenges by the Soviet Union in Greece and Berlin. US military forces remained at a level of about 1.5 million personnel until the Korean War in 1950.
