Modern Military Helmet

 

Modern military helmets, made of lightweight but sturdy materials, are designed to protect the head from bullets and from shell and grenade fragments.
The Helmet, protective covering for the head, generally made of metal, leather, or plastic, used in warfare, certain occupations, and sports. Military helmets have been worn from the earliest times and have been made in many different forms. The simplest form, a close-fitting skullcap, apparently made of iron, leather, and bronze, is represented on Assyrian reliefs. Elaborations of this form were used by the Greeks, Etruscans, and the late Romans and included protective devices for the neck and face, and plumes or carved figures that surmounted the crown.
