FIRST TO MAINTAIN
Crimson and yellow are colors traditionally associated with the Ordnance Corps. The division of the shield is representative of the numerical designation of the unit.
The sea lion alludes to the arms of the President of the Philippines; it commemorates the action in World War II for which the parent organization was awarded the Philippine Presidential Unit Citation. The green roundel bearing the Seal of Solomon stands for the Solomon Islands and refers to the parent unit's participation in that campaign. The branch of coconut palm stands for service on Luzon, the largest of the Philippine Islands, which lead the world in the growing of coconut. The palm is a symbol of military victory; also, because of its extensive use for food, clothing and shelter, it refers to the maintenance function of the Battalion.
The coat of arms was originally approved for the 1st Ordnance Battalion on 21 Mar 1942. It was rescinded on 10 Oct 1955. The insignia was approved for the 1st Maintenance Battalion and amended to add a crest and change the motto on 14 Feb 1967. The coat of arms was amended with blazon of the crest and symbolism revised on 11 Jan 1993.
