The 46th Military Police Command Distinctive Unit Insignia (DUI), often referred to as a “unit crest,” was approved for wear on 21 November 2006. Its efforts as part of both the Michigan Army National Guard and U.S. Army North to provide a swift and expert response in the event of a Chemical, Biological, Radiological, and Nuclear (CBRN) disaster is the primary role it plays in “Securing Freedom Worldwide," the unit’s officially recognized motto.
A key taken from the Brigade’s Shoulder Sleeve Insignia forms the focal point of the unit crest, with the teeth on the working end of the key shaped to form the Roman numerals for 4 and 6 and thus signify the Command’s numerical designation (the Command is also a part of Task Force 46). The key’s handle is also in the shape of a hexagon, which is the overall shape of the Command’s Shoulder Sleeve Insignia. A griffin’s head in the upper right is a symbol of readiness, vigilance, and watchful security; the unsheathed sword in the bottom left represents the strength and combat power at the unit’s disposal.
G
uidance on wear of the DUI is found in DA Pamphlet 670-1, Section 21-22, "Distinctive unit insignia" and 21–3(d) and (e), "Beret" and "Garrison Cap," respectively.
