MACHINAMENTUM DE VITAE (The Machine of Life).
Buff and blue are traditional colors of the Quartermaster Corps. The cottonmouth snake is native to Oklahoma. The tongue is shaped as a red thunderbird which represents the old Oklahoma 45th Division, the roots of the Oklahoma Army National Guard. The blue venom drops represent the Quartermaster Corps ability in the water purification process. The wavy counter wavy lines divide the black venom drops which represent the unpurified water from the white venom drops which represent the purified water.
The crest is that of the Oklahoma Army National Guard.
The coat of arms was approved on 6 March 2006.
