Lore reasoning: During battles of early WW2, commanders found a lot of friendly fire incidents were caused by opposing units having similar colored uniforms and/or no clear symbology of equipment so it was hard to identify friend from foe (even harder from afar). later in the never-ending war, all sides of the war started introducing more easily identifiable uniforms and gear

Creative liberty reasoning: I am not aiming for total historical accuracy, and national flags/symbols aid players in positively identifying friend and foe on the virtual battlefield. I am taking some creative liberty with the retextures so you can differentiate between nations while playing
