The dovetail suggests the keystone symbol of the state and alludes to coordinated support, the unit's mission. The torii gate represents the Korean War and the Meritorious Unit Commendation awarded the former unit, with the partition of the shield referring to the 38th Parallel. The althea blossom, taken from the flag of the President of Korea, symbolizes the two Republic of Korea Presidential Unit Citations and the eight battle honors awarded the former unit for the Korean War.
