Based on the British Army MK7 helmet. The Mark 7 helmet is the current general issue combat helmet of the British Armed Forces supplied by NP Aerospace. Officially known as the GS (General Service) Mark 7 combat helmet, it replaced the previous Mark 6A helmet and Mk 6 helmet, introduced in 2005 and 1982 respectively.
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.
