The white "card suit" stencils on the sides of the soldier's helmets in the film are accurate. The WWII 101st Airborne Division used the different suits to identify their three parachute infantry (diamonds, hearts, and spades) and one glider infantry (clubs) regiments. A white "tic" at either the twelve, three, six or nine o'clock positions around the suit indicated Headquarters, 1st, 2nd, or 3rd Battalions, respectively. The soldiers in "Battleground" wear the club suit of the 101st's 327th Glider Infantry Regiment, with a "tic" at the nine o'clock position, indicating they belong to that regiment's 3rd Battalion.
