 The infantry battalions consisted of 806 men in four rifle companies, each with four platoons along with a support company consisting of two Anti-tank platoons each with four 6 pounder guns, two mortar platoons armed with six 3 inch mortars, and two Vickers machine gun platoons.These battalions were larger than those from the Parachute Regiment.Initially the American Glider Infantry Regiments (GIR) had only two battalions, but later in Europe, the two battalions of the 401st GIR were divided in March 1944 to act as the 3rd battalions of the 325th and 327th GIRs.
