Shield
Brick red and golden yellow are the colors traditionally used by the Transportation Branch. Red is emblematic of valor and sacrifice. The annulet is symbolic of the wheel, the basis of transportation. The fleur-de-lis in gold represents the unit's service in Northern France during World War II and the lion is for action in Normandy. The wavy blue bar symbolizing water recognizes participation in the Rhineland campaign and is reminiscent of the unit's origin as the 417th Port Battalion. Each of the two white stars represents five of the unit's Korean campaign credits and the wings indicate the Battalion's support to the Army aviation program.
Crest
The swords commemorate the unit's thirteen decorations for service during World War II, Korea, Vietnam and the Southwest Asia Conflict. The triangle's points allude to these three wars, with the oriental dragon underscoring the battalion's Vietnam War service. The triangle suggests a delta, referring to the Mekong River Delta of Vietnam. Red is the color of courage and sacrifice; green refers to the tropical nature of Southeast Asia; and gold is emblematic of honor and high achievement.
The coat of arms was approved on 26 June 2003. It was amended to correct the symbolism of the crest on 1 July 2010.
