The 442nd Infantry Regiment Distinctive Unit Insignia—DUI for short, or “unit crest” informally—was approved 22 May 1952. The taro leaf, also used on the coat of arms of the 100th Infantry Battalion (technically the 1st Battalion, 442nd Infantry Regiment), is commonly identified with Hawaii, the unit's home area. A Mississippi River steamboat is used as symbol for Mississippi in general and Camp Shelby—site of the unit’s activation 1 February 1943— in particular. “Go For Broke,” the unit motto, was actually adopted by the Regiment from a Hawaiian pidgin phrase used by gamblers to mean staking everything on a single roll of the dice in a game of craps.
A Distinctive Unit Insignia (DUI) is 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 (Enlisted only) with the base of the insignia toward the outside shoulder seam.
Enlisted personnel wear the insignia centered on a shoulder loop by placing it an equal distance from the outside shoulder seam to the outside edge of the shoulder-loop button. Officers (except Generals) wearing grade insignia on the shoulder loops center the DUI by placing it an equal distance between the inside edge of the grade insignia and the outside edge of the button.More guidance on wear of the DUI is found in DA Pamphlet 670-1,
Section 21-22, "Distinctive unit insignia."
