Helmets

Helmets protect infantry from instant kill headshots. However not only helmets protect from headshots. Field Caps and Tanker Hats also provide a one time protection from a deadly headshot. Each nation has their own unique helmet with a few variations to them as well. No helmet is better than the other, they all protect equally and they all fly off a soldier's head once shot. You can also run over to the helmet and pick it up, a helmet can withstand an unlimited amount of shots but must be picked up each time it is shot off.
