SUPPORTING YOUR INTENT.
Buff and scarlet are the colors traditionally used by Support organizations. Red represents courage and zeal; gold is emblematic of honor and high achievement. The blue shield and wavy chief reflect the location of the battalion in the Caribbean. The crossed sword and key underscore the unit's mission, while the embattled chevron symbolizes strength and support and highlights fortification and defense. The five battlements represent combat service support's sustaining imperatives (anticipation, continuity, responsiveness, integration, and improvisation). The sentry box reflects the organization's cultural heritage within the Puerto Rico area of operation. Red and gold reflect the Spanish history of the island.
The crest is that of the Puerto Rico Army National Guard.
The coat of arms was authorized on 10 Mar 1997.
