The Military Police Corps, the uniformed law enforcement branch of the U.S. Army.

 The Military Police Corps, the uniformed law enforcement branch of the U.S. Army, was officially established on September 26, 1941.

During World War II, Military Police schools were established at Camp Gordon and Fort Benjamin Harrison, and MPs also trained for port security at Fort McHenry.

Military Police soldiers moved traffic along the Burma Road, supported amphibious operations on Normandy beachheads, and managed enemy prisoners of war from Italy to the South Pacific.

 Thanks to the actions of 1LT John "Jack" Hyde and his detachment of MP, The Corps was heralded for gallantry at Remagen, as a fighting force in numerous combat actions and as peacekeepers at war’s end.

In 1944, the Army saw the need for a unit to investigate crime involving soldiers in Europe. 

The United States Army Criminal  Investigation Division was established as a branch of the Provost Marshal General’s Office and has continued investigative activity since

After the war ended, cavalry units in Germany were utilized to form the United States Constabulary, a police-like patrol organization. It was disbanded in the 1950s.

In 1949, the newly formed Defense Department was in the process of reorganizing the Army and plans were developed to disband the Military Police Corps.

 But when Congress passed the Army Reorganization Act in May 1950, the Corps survived, remaining a separate branch of the Army.
