A bulletproof helmet is a single soldier's head protective equipment, mainly used to resist damage to the head from projectiles or fragments. Its core function is to protect the wearer from fatal injuries in the battlefield or high-risk environments. The structure usually consists of a helmet shell, suspension cushioning system and face mask, and is made of advanced materials such as polyethylene, titanium alloy and Kevlar fiber to improve protection while reducing weight; models such as Browning bulletproof helmets also integrate neck protective cape components to optimize wearing comfort and defensive range
