They also represent the invasions of the Bismark Archipelago and Leyte. The arm grasping the lighting flashes alludes to the mission of the unit enabling information and orders to be sent and received. The seven lightning flashes commemorate the seven decorations awarded the unit for services in World War II and Korea. The temple refers to actions in Korea during the Korean War.
