During the broadcast of the tv-series 'Band of Brothers', you may have noticed that paratroopers of the 101st Airborne Division wore on the side of their helmet a white stencil. After the drop it was of importance that the men were quickly assembled and went to their own unit. In the chaos of the jump many men got mingled. Every unit or supporting battalion had for that purpose a white identity mark on both sides of the helmet. Just prior to the drop in Normandy they were placed only on the outerhelmet, but later also on the inner helmet. Some regiments got an additional marker on one site of the stencil to show to which headquarters (tick at 12 o'clock) or battalion (tick under or sideways of the stencil) the bearer belonged.

The Parachute Infantry Regiments had playingcard motives (see below). After the jump over Normandy it was noticed that the 3th battalion of the 506th had their 'tick' on the wrong site, in stood at 3 o'clock instead of 9 o'clock (the position of the 1st battalion). Later in the war it was corrected. Senior officers and non-commissioned officers (NCO.) wore an extra tick on the back of their helmet. This became a target for sharpshooters and was in many cases removed during the war.

Below are two stencils of supporting units. The first is the (three leaved) clover of the 327th Glider Infantry Regiment. A regiment that were brought in by gliders. The second is a white triangle of the 81st Airborne Anti-Aircraft and Anti-Tank Battalion.

Below are white circles to be seen of the artillery units of 101st Airborne Division. The 377th and 463rd Parachute Field Artillery and the 907th and 321st Glider Field Artillery could be recognized by these white 'balls'.

The next two units of the 101st Airborne Division had a good recognizable symbol. The first was a white cross of 326th Airborne Medical Company. The engineers of the 101st wore a capitol 'E' for a symbol. It stood for the 326th Airborne Engineer Battalion.

Finaly a symbol that was just on a few helmets of the 101st Airborne Divsion. These, a lyre, were only carried by the members of the Division Band.

Below is a explanation of the placement of the 'tick' near the symbol of the unit. As example I show four 'diamond' symbols of the 501st Parachute Infantry Regiment (PIR).
