Combat helmet
A combat helmet, also called a ballistic helmet, battle helmet, or helmet system (for some modular accessory-centric designs) is a type of helmet designed to serve as a piece of body armor intended to protect the wearer's head during combat. Helmets designed for warfare are among the earliest types of headgear to be developed and worn by humans, with examples found in several societies worldwide, the earliest of which date as far back as the Bronze Age.
