31st Engineer Battalion — "We Demonstrate"

Some units don’t just serve — they build the road everyone else walks on. The 31st Engineer Battalion has been doing exactly that since 1940, activated at Fort Belvoir, Virginia and forged through WWII into one of the Army’s most enduring combat engineering legacies at Ft. Leonard Wood, Missouri.

This classic tee is made to carry that story.

Cut from 100% combed ringspun cotton and preshrunk for lasting shape, it’s the kind of shirt that gets better with every wear. Double-needle sleeve and bottom hems keep it looking sharp long after the first wash. Clean, structured, and built to last — just like the unit it honors.

Wear the history. Honor the mission.

• 100% combed ringspun cotton — preshrunk to minimize shrinkage
