The Army Military Police School, which trains police for the Army and Marine Corps, is located in Fort Leonardwood, Missouri. The U.S. Navy and Air Force has their own law enforcement school at the Lackland Air Force Base in San Antonio, Texas.
Prospective military police officers must enlist or be commissioned in a branch of the U.S. Military to train at these schools. Job training for military police in these branches, not including Basic Combat Training or Marine Corps Recruit Training, is 11 weeks of classroom instruction, field training and directive experience. Military police protect government installations and property, enforce military laws and regulations, control traffic, prevent and investigate crimes, and respond to emergencies.
