Coats of arms of U.S. Infantry Regiments

Coats of arms of U.S. infantry regiments are heraldic emblems associated with infantry regiments in the US Army. Under Army Regulation 840-10, each regiment and separate table of organization and equipment (TOE) battalion of the U.S. Army is authorized a coat of arms to be displayed on the organization's flag, called the "colors."^[1] This coat of arms usually forms the basis for the unit's distinctive unit insignia (DUI), the emblem worn by all members of the unit on their service uniforms.^{[citation needed]}

The coats of arms for infantry units normally incorporate the color blue, which has been the traditional color of the infantry in the U.S. Army since 1851.^[2] Below are galleries of the coats of arms of US Army infantry regiments. The official mottoes (as awarded by The Institute of Heraldry of the U.S. Army) and/or special designations (as awarded by the United States Army Center of Military History) of the units are also noted.

Active duty units that have served in war are authorized a crest. National Guard units are authorized the crest for their respective state, while Army Reserve units are all authorized a crest depicting a minuteman.^[1]
