Also known as unit crests, Distinctive Unit Insignias (DUIs) are worn by all Soldiers (except General Officers) in units that have been
authorized to be issued the device. The device is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (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.
Full guidance 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.

Though its lineage can followed back to the start of the 1920s, the 167th Theater Sustainment Command has been serving as a Support unit with the full understanding that “They Rely On Us”—with “They” being both the units they directly support as well as the citizens of this nation —for over fifty years. Previously an Infantry unit, it was designated as the 167th Support Brigade on 15 January 1968, with subsequent redesignations reorganizations retaining the numerical designation as it became a Support Command (1976), a Sustainment Command (2006), and finally a Theater Sustainment Command (TSC). As of Winter 2024, the 167th TSC remains an active unit in the Alabama Army National Guard and is headquartered at Anniston, Alabama.
The 167th Theater Sustainment Command Distinctive Unit Insignia was first approved when it was Brigade on 12 June 1970. Gold (buff) and scarlet are used throughout to reflect its role in Support, while the blue and white are employed as a nod to its Infantry roots. A heraldic stairstep “mountain” is reference to Red Mountain outside Birmingham in the unit’s home state of Alabama.
A seven-pointed white star on a blue arrowhead is an allusion to its service in the Pacific during World War II; the star is from the flag of Australia and denotes New Guinea, which is where the Command earned an Arrowhead for taking part in an assault landing. The crossed machetes are a symbol of the Philippine Islands and reflect the Commands participation in Southern Philippines campaign; the colors of blue, white, and red are taken represent the Republic of the Philippines and the Philippines Presidential Unit Citation the unit received for its service with the 31st Division in the Second World War.
