U.S. ARMY 10TH INFANTRY REGIMENT UNIT CREST (DUI)

The 10th Infantry Regiment was constituted in the Regular Army as the 10th Infantry on 3 March 1855 and was organized the next month at Carlisle Barracks in Pennsylvnia. All four battalions of the Regiment—1st, 2nd, 3rd, 4th—were constituted as Companies in the Regiment at the same time. In addition to Civil War campaigns, the Regiment fought in the Indian Wars (with some battalions receiving credit for more campaigns than the two credited to the Regiment), War With Spain, Philippine Insurrection, and World War II (five campaigns). By the mid-1990s, all the Regiment’s battalions had been transferred to U.S. Army Training And Doctrine Command, with the 2nd and 3rd Battalions still active as of Summer 2023 and conducting training at Fort Leonard Wood, Missouri.Approved on 25 November 1922, the 10th Infantry Regiment Distinctive Unit Insignia (DUI), sometimes called a unit crest, features a prominent Roman numeral “X” to indicate the unit’s numerical designation. It is superimposed on an officer’s sword styled after the dress sabers carried at the time the Regiment was organized. A circular band with the unit motto “Courage And Fidelity” recalls straps of knapsacks and belts worn by Infantry in the 1850s; the motto is taken from a speech given at the presentation of the regimental colors at Carlisle Barracks in September 1855, the same year the Regiment was formed and which is memorialized by the Roman numerals for 1855 (MDCCCLV).


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.
