When the U.S.A. entered World War Two, after the attack on Pearl Harbor, they began using national identification marks.
The mark, usually a white star, was placed on five locations on the AFV's. During the war years teh star didn't undergo
many changes, although it was sometimes omitted.
Changes to the National Identification Mark
1942 - Operation Torch - landing in North Africa, a white star with a stripe encircling the turret was commonly used
on M3 series tanks.
1943 - the stripe was deleted and the white star was surrounded in a white circle.
1944 - Before the Normandy landings the white star, with either a continuous or broken white circle, was standardized
for all of teh Allied forces except USSR.
