Crimson is the color traditionally associated with Ordnance units. The pale denotes the Battalion's military determination. The spanner, a medieval wrench used to tighten wheel lock firearms symbolizes maintenance, the unit's past mission and branch affiliation. The Torii gate alludes to World War II service in Okinawa.
The pellets signify munitions and the mission of the Battalion. The phoenix, adapted from the State Seal of Hawaii, represents resurrection, suggesting the Battalion's reactivation from a Maintenance to an Ordnance organization.
