Shield
Crimson and yellow are colors traditionally associated with the Ordnance Corps. The Battalion's campaign participation in Northern France, World War II, is denoted by the six-pointed black star from the coat of arms of Cherbourg, France, which is near Quetthou where the Battalion performed its initial combat support mission. The two lightning flashes, "V"-shaped, and the white circular form are suggested by the shoulder sleeve insignia for European Theater of Operations, U.S. Army, worn by the unit in World War II. The flashes supporting the bomb burst also signify the former munition support mission of the Battalion.
Crest
The chevron signifies support, representing the branch affiliation of the unit. The gray heraldic dragon, a symbol of assertiveness and a courageous defender, implies the unit's special designation "STEEL DRAGONS." The two red fleurs-de-lis indicate the Battalion's campaign participation during World War II in Northern France. The star is reminiscent of the star from the Texas state flag, alluding to the state where the 72d Support Battalion will activate.
The coat of arms was originally approved for the 72d Ordnance Battalion on 26 February 1993. It was redesignated for the 72d Support Battalion and amended to add a crest effective 17 July 2011.
