CH252 helmet

The CH252 helmet is the standard issue helmet worn by the members of the UNSC Marine Corps, UNSC Army, and UNSC Air Force; it is an integral component of the Marine and Army Battle Dress Uniforms. It has been in service since the Insurrection. Nicknames for the helmet include "Coconut", "Lid", "Can", and "Pasta Shell".

Description
The standard helmet weighs 3.3 pounds. When worn with the Marines' M52B body armor, the helmet is typically painted olive drab, though when worn with other body armor models, the helmet is painted to match the body armor. Within the Army, the helmet is generally painted tan, dust gray, or olive drab; medics' helmets feature a caduceus. Air Force pilots' helmets are painted dull brown, similar to those of many Marines.

The helmet can be outfitted with ballistic goggles or a heads-up display eyepiece that can be polarized either orange or black, as well as a boom microphone and a tactical flashlight. The helmet can be fitted with an accessory clip which can be used to mount a night vision device. The basic Army configuration of the helmet features a chin strap, though this is typically not worn by Marines. Balaclavas are often worn with the helmet, especially when operating in frigid environments, though they are occasionally worn in temperate and desert climates.

The helmet can be fully enclosed and environmentally sealed; this sealed configuration is the basis of the Beta-5 Division's military police helmet, which can sport a polarized or unpolarized visor. It is a shared asset among the UNSC's military branches. This version can be used with vacuum suits during both extra-vehicular activity and terrestrial combat, as it can provide protection from the environmental hazards caused by nearby glassing. This variation is standard-issue for the Air Force's UH-144 Falcon and YSS-1000 Sabre pilots. The Beta-5 MP helmet can also be used in conjunction with MJOLNIR armor. The helmet worn by Orbital Drop Shock Troopers also seems to be derived from the CH252 helmet.

A variation of the CH252 helmet was worn by the officers of the New Mombasa Police Department. This version featured a large blast shield to protect the wearer from small arms' fire and presumably from shrapnel and secondary explosions. Like its military counterparts, the NMPD's version of the CH252 could mount a boom microphone.
