A gold color metal and enamel device 1 1/8 inches (2.86 cm) in width overall consisting of six radiating gold spears issuing from behind the apex of a red chevron surmounted at the base on either side by three gold spears and all enclosed by a continuous blue scroll of three folds, looped from the base on each side and arched at the center and inscribed SUPPORT FOR COMBAT in gold letters.
The chevron, a heraldic support symbol between the formations of spears, symbolizes the support capabilities and basic mission of the organization. The gold spears further simulate rays and represent the guidance, planning and technical supervision over mission operations of the organization and subordinate units. The spear points, three, six and three represent the numerical designation of the Battalion.
The distinctive unit insignia was originally approved for the 363d General Support Group on 28 March 1972. It was redesignated for the 363d Support Group on 11 July 1972. The insignia was redesignated for the 363d Quartermaster Battalion with the description and symbolism updated effective 16 September 2000.
