A Gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a shield blazoned as follows: Gules (Crimson) on a chevron Or six hurts. Attached below the shield a Gold scroll inscribed "SERVIAMUS" in Blue letters.
Crimson and yellow (gold) are used for Ordnance and indicates the unit's origin. The chevron is suggested by the coat of arms of the 107th Quartermaster Regiment, through which this Battalion inherits Spanish War and World War I history. The blue circles represent the Battalion's six battle honors for the Spanish War and World War I, in which the unit served as Infantry. The circles also simulate wheels and allude to its transportation duties in World War II. The motto translates to "We Serve."
The distinctive unit insignia was originally approved for the 732d Ordnance Battalion on 15 February 1954. It was amended to correct the spelling of the motto on 10 June 1954. It was redesignated for the 732d Maintenance Battalion on 11 June 1964. The insignia was redesignated effective 1 September 2008, for the 732d Support Battalion with the description and symbolism updated.
