Coats of arms of US Army units are heraldic emblems associated with units in the US Army. Under Army Regulation 840-10, each regiment and separate table of organization and equipment (TOE) battalion of the US Army is authorized a coat of arms to be displayed on the organization's flag, called the "colours". 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.
The coats of arms of units that have been redesignated are shown under their most recent branch.

Field Artillery
The coats of arms for artillery units normally incorporate the color red, which has been the traditional color of the Artillery Branch in the US Army since the formation of the Corps of Artillery in 1777. In 1917 the numbers from 1 through 100 were reserved for the Regular Army, from 101 through 300 for the National Guard, and 301 and above for the National Army (later Army Reserve). Under this system the 1st through 21st and 76th through 83d were organized in the Regular Army; the 101st through 151st, in the National Guard; and the 301st through 351st, plus the 25th through 75th and the 84th and 85th, in the National Army. Several numbers in national guard units have been "reused" so that its possible to have two units with same number, but at different time periods. The units below include both regiments and battalions.

Special Troops/Sustainment Troops
The coat of arms below are listed as the Institute of Heraldry lists them on their webpage. All divisional-level special troops battalions have been redesignated as 'Sustainment Troops'. It should be noted that most of the former Special Troops Battalions for brigades were reflagged as Engineer Battalions in 2018 and 2019, while divisions reflagged them as Division Sustainment Troops Battalions.

Support
'Support units' are those which do not fall under the category of Transport, Ordnance, or Quartermaster. Rather they are typically a mix of all of these, plus elements of the Medical Corps and Military Police depending on role. Most support battalions were previously quartermaster and ordnance battalions, but not all.
