Introducing project “Military Insignia”, featuring top quality military heraldry designs. Here you will find designer apparel, accessories, custom postage and gifts decorated with insignia of the 10th Infantry Regiment DUI The 10th Infantry Regiment is a regiment in the United States Army, constituted 3 March 1855 in the Regular Army as the 10th Infantry and organized in April 1855 at Carlisle Barracks, Pennsylvania. In June 1957 the regiment was relieved from assignment to the 5th Infantry Division and reorganized as a parent regiment under the Combat Arms Regimental System. In June 1989, it was withdrawn from the Combat Arms Regimental System, reorganized under the United States Army Regimental System, and transferred to the United States Army Training and Doctrine Command. The distinctive unit insignia was approved on 24 Nov 1920. The Roman numeral “X” signifies the numerical designation of the regiment; the sword is representative of the dress sabers carried by the officers of the regiment when it was organized. The circular band is indicative of the knapsack straps and waist belts, like those if the French chasseurs-a-pied, worn by the 10th Regiment in the late 1850's. The motto is taken from an address made by Colonel Edmund B. Alexander, first colonel of the regiment, upon the occasion of the presentation of the regimental colors at Carlisle Barracks, Pennsylvania, in September 1855. The Roman numerals “MDCCCLV” signify the year the regiment was constituted and organized.
