The U.S. Army Military Police School Distinctive Unit Insignia—also called a DUI or “unit crest”—was originally approved for the Military Police School on 6 May 1948. It as redesignated for the Provost Marshall General’s School on 8 February 1952, followed nearly three years by a final redesignation reflecting the school’s current title. Green and gold, the branch colors of the Military Police Corps, are used exclusively for the insignia, which comprises a shield portion above a scroll containing an inscription that reads JUSTITIA ET VIRTUS (“Justice And Valor”). The school’s mission of instruction and guidance is symbolized by an owl holding the scales of justice in its beak.
Distinctive Unit Insignias are worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (ASU, Enlisted only) with the base of the insignia toward the outside shoulder seam. DUIs are not worn on the Dress variations of either uniform, however.

Located at Fort Leonard Wood, Missouri, the U.S. Army Military Police School trains over 20,000 students every year in both basic and advanced law-enforcement principles, tactics, procedures, and regulations. While the Military Police Corps can rightfully trace its origins to the creation of the staff position of Provost Marshall by George Washington in 1776 and the Congressional establishment of a Provost Corps in 1778, the Military Police Corps did not become a separate branch of the Army until 1950, when the Army Reorganization Act made permanent the Military Police Corps that had been established on 26 September 1941 by order of the Secretary of War Henry Stimson.
