KEYSTONE TO VICTORY.
Shield
Oriental blue is the primary color traditionally associated with the Military Intelligence branch. The demi-griffin stands for courage, intelligence and vigilance and holds a key as the symbol of secrecy and security. The wards of the key form a keystone recalling the Battalion's motto, home state of Pennsylvania and the unit's Capstone mission to the 28th Infantry Division. The checky chief, recalling the insignia of the 99th United States Army Reserve Command, suggests strategy, while its colors, black and white, refer to night and day operations. The sword represents military preparedness; the lightning flash suggests speed and electronic capabilities. Gold stands for excellence.
Crest
The crest is that of the United States Army Reserve.
The coat of arms was approved on 21 August 1991.
