The lightning flash in the colors of the Signal Corps symbolizes the rapid communication provided by the Battalion. The blue foot with white fimbriation represents the ocean waves, exemplifying the many amphibious operations conducted by the Eighth Army during World War II and supported by this organization. The engrailed line across the shield is representative of the typical shoreline of the islands assaulted. The gray upper portion of the shield is symbolic of the early morning sky during an amphibious attack.
The design commemorates the actions for which the battalion received unit decorations during World War II and in the Korean War. The sea-lion, from the flag of the President of the Philippines, refers to the unit's service in the Leyte campaign. The trumpet or bugle symbolizes Army communication--the Battalion's function. The two stars on the red and blue tabard stand for the actions in Korea for which the battalion received two Meritorious Unit Commendations.
