Buff is a color traditionally associated with Supply and Service and Quartermaster organizations, the original allocations of the units. The gold keys reflect control over supplies and refer to the unit's origin as the 142d Quartermaster Battalion. The buff color also symbolizes sand and refers to the former unit's World War II campaign credits earned in Africa and the Middle East. The Taeguk reflects that Battalion's service during the Korean War. The short sword exemplifies the unit's motto and alludes to combat participation.
The mill rind represents the Support mission. World War II campaigns in Europe, Africa, and the Middle East are recalled by the straight sword, quiver with arrow, and the scimitar respectively. The scimitar also represents Operation Iraqi Freedom campaigns. The Taeguk refers to service during the Korean War. Scarlet denotes courage and sacrifice.
The coat of arms was originally approved for the 142d Supply and Service Battalion on 18 February 1993. It was redesignated for the 142d Support Battalion with symbolism revised on 23 June 1993. It was amended to include a crest on 16 October 2006.
