ShieldThe service of the former organization, the 260th Antiaircraft Artillery Battalion, is indicated by a red shield for Artillery. The white oblong bearing the red diamond was the device used on the guns, tractors, and other property of the 2d Battalion, 60th Regiment Coast Artillery, from which the battle credits of the 260th Coast Artillery are derived. The fleur-de-lis denotes service in France. The prickly pear cactus symbolizes the Mexican Border service of the Cavalry and Field Artillery units assigned to the 260th Coast Artillery. The pile with the two projectiles represents the constitution of the unit as one searchlight battery and two gun batteries when the assignment to antiaircraft armament was made.
CrestThe crest is that of the District of Columbia Army National Guard.
