The 175th Military Police Battalion Distinctive Unit Insignia, commonly called a “unit crest” or a DUI, was approved on 24 October 1952. Its green and yellow hues signify the unit as part of the Army’s Military Police branch, and the unit’s function is symbolized the scales of justice. A “houn’ dawg” in the canton (red inset) is a reference to the descent of the Battalion from the 203rd Coast Artillery. “Strength And Justice” has been the unit motto since the insignia was approved.
