31st Engineer Battalion — "We Demonstrate"
Constituted 1940. Proven in combat. Worn with pride.
The 31st Engineer Battalion didn't earn its motto in a briefing room. From its activation at Fort Belvoir in 1940 — through redesignation as the 31st Engineer Combat Battalion in December 1941, and its evolution into the 31st Engineer Combat Regiment by August 1942 — this unit demonstrated what combat engineers do best: they build, breach, and lead the way under fire.
This hoodie is a tribute to that legacy. Every stitch is a nod to the soldiers who shaped the battlefield so others could advance.
