The Stahlhelm is a German military steel combat helmet intended to provide protection against shrapnels and fragments or shards of grenades. The term Stahlhelm refers both to a generic steel helmet and more specifically to the distinctive German military design.

A combat helmet or battle helmet is a type of helmet. It is a piece of personal armor designed specifically to protect the head during combat. Modern combat helmets are mainly designed to protect from shrapnel and fragments, offer some protection against small arms, and offer a mounting point for devices such as night-vision goggles and communications equipment.
