Symbolism:
Shield: 
The blue field is for the Infantry, the 506th's arm of the service. Thunderbolt indicates the regiment's particular threat and technique to attack: striking with speed, power, and surprise from the sky. Six parachutes represent the fact that the 506th was in the sixth parachute regiment activated in the U.S. Army, of which, the unit is proud. The green silhouette represents the Currahee Mountain -- the site of the regiment's activation (Taccoa, Ga.) -- and symbolizes the organization's strength, independence, and ability to stand alone for which paratroops are renowned.

Crest:
The winged sword-breaker represents airborne troops. The conjoined caltraps stand for the enemy line of defense behind which paratroopers are dropped. They are two in number in reference to the unit's two air assault landings. The fleur-de-lis is for the Normandy invasion and the bugle horn, from the arms of Eindhoven, Holland, refers to the organization's capture of that objective. The six large spikes of the caltraps stand for the unit's six decorations. The demi-roundel represents a section of the hub of a wheel. It stands for Bastogne, Begium, strategic crossroads of highways and railways. The hub, surmounted by the winged sword-breaker, commemorates the organization's heroic defense of Bastogne in the Battle of the Bulge.

Motto: 
CURRAHEE. American Aboriginal, Cherokee Tongue meaning "Stands Alone.".
