The shield is in the colors of the Ordnance Corps. The two crosses pattée recall that the predecessor organization was cited by the French Army for action at Kasserine and at the Normandy beachhead. The Maltese crosses represent the organization's two citations awarded by the Belgian Army for action at Mons and at Eupen-Malmedy.
The colors yellow and red, suggested by the national flag of Vietnam, allude to the 701st Maintenance Battalion's participation in eleven campaigns there. The wrenches, symbolic of the maintenance mission, have scarlet handles representing two awards of the Meritorious Unit Commendation. The four spearheads joined together symbolize the Cross of Gallantry and the green palm branches bound in red are in the colors of the Civil Action Honor Medal, two decorations awarded by the Republic of Vietnam.
