Blue is the color of the Infantry. The open parachute symbolizes the parachute functions of the regiment and the lightning flash indicates the speed by which the allotted duties are performed.
The black widow spider was the unofficial symbol of the unit in World War II, black and orange being the colors associated with the unit. The lightning bolts represent two airborne assaults; the blue bolt recalls the Presidential Unit Citation for action on the Contentin Peninsula; the gold refers to the shoulder sleeve insignia of the 17th Airborne Division, of which the unit was a part. The bolts also represent action from the sky and the speed with which allocated duties are performed. The oak sprigs symbolize service in the Ardennes during the Battle of the Bulge. The key refers to the Rhineland as the key to Germany's heartland.
The coat of arms was originally approved for the 507th Parachute Infantry Regiment on 21 Jan 1943. It was redesignated for the 507th Infantry Regiment and amended to add a crest and update the shield symbolism on 4 Feb 1986.
