The '''CH252 helmet''' is the standard issue combat helmet worn by the members of the [[UNSC Marine Corps]], [[UNSC Army]], and [[UNSC Air Force]]; it is an integral component of the [[UNSC Marine Corps Battle Dress Uniform|Marine]] and [[UNSC Army Battle Dress Uniform|Army Battle Dress Uniforms]]. It has been in service since the [[Insurrection]].<ref name="Origins"> '''Halo Legends:''' ''Origins''</ref> [[Ushuaia Armory]] was involved in the development of the helmet,<ref>'''[[Halo: The Essential Visual Guide]]'''</ref> though [[Misriah Armory]] is known to manufacture it,<ref>'''Halo: Arms Race'''</ref> either in lieu of or in addition to Ushuaia.

==Overview==
The standard helmet weighs 4 lbs (1.8 kg).<ref name="HE">'''[[Halo Encyclopedia]]''', ''page 49''</ref> 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.<ref name="HW">'''Halo Wars'''</ref><ref name="H:R">'''Halo: Reach'''</ref><ref>'''Halo: Combat Evolved'''</ref><ref name="Origins"/><ref name="HC">'''Halo Legends:''' ''Homecoming''</ref> Within the Army, the helmet is generally painted tan, dust gray, or olive drab; medics' helmets feature a [[Wikipedia:Caduceus|caduceus]].<ref name="H:R"/> Air Force pilots' helmets are painted dull brown, similar to those of many Marines. In the Marine Corps, the name of the wearer is sometimes stenciled on the back of the helmet,<ref>'''Halo: Combat Evolved''', campaign level ''[[343 Guilty Spark (level)|343 Guilty Spark]]''</ref> though this is not always the case.

The helmet can be outfitted with a [[heads-up display|heads-up display]] [[UNSC tactical eyepiece|eyepiece]] or ballistic goggles 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.<ref name="H:R"/> Balaclavas are often worn with the helmet, especially when operating in frigid environments, though they are occasionally worn in temperate and desert climates.<ref name="HW"/><ref name="HC"/>

UNSC personnel have created several nicknames for the helmet, including "coconut", "lid", "can", and "pasta shell".<ref name="HE"/>

==Variations==
===ECH252 helmet===
The ECH252 is an enclosed variant of the standard CH252 helmet.<ref>'''Halo Encyclopedia (2011)''', ''page 57''</ref> The helmet can be fully enclosed and environmentally sealed, featuring either a polarized or unpolarized visor; this sealed configuration is the basis of the [[Beta-5 Division]]'s [[military police]] [[MJOLNIR Powered Assault Armor/Mark V(MP)|helmet]], which is a shared asset among the branches of the [[UNSC Defense Force]]. This version can be used with [[vacuum suit]]s during [[extra-vehicular activity]].<ref>'''Halo: Reach''', campaign level ''Long Night of Solace''</ref> It is also utilized during terrestrial combat as part of the Marine Corps' Atmospheric/Exoatmospheric (A/X) BDU,<ref>[http://halo.xbox.com/forums/games/f/5/p/7250/70316.aspx#70316 '''Halo Waypoint Forums''': ''The UNSC Army discrepancy in CE can be fixed'']</ref>, which can provide protection from the environmental hazards caused by [[glassing]].<ref>'''Halo: Reach''', campaign level ''[[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]''</ref> This variation is standard-issue for the Air Force's [[UH-144 Falcon]] and [[YSS-1000 Sabre]] pilots. The Beta-5 Division's MP helmet can also be used in conjunction with [[MJOLNIR Powered Assault Armor|MJOLNIR armor]].<ref name="H:R"/> When the user speaks with the non-MJOLNIR variant, the mouthpiece that encloses the helmet moves in tandem with the lower jaw.<ref name="H:R"/>

===ODST helmet===
{{Main|ODST armor}}
The standard helmet worn by [[Orbital Drop Shock Trooper]]s, which was originally designed for use with the MJOLNIR system,<ref>'''Halo: Reach''': ODST helmet Armory description: ''"Many technologies initially developed for MJOLNIR have gained widespread adoption."''</ref> was also derived from the CH252 helmet. Like the Beta-5 Division MP helmet, the ODST helmet is enclosed and can provide oxygen for fifteen minutes; unlike the Beta-5 Division MP helmet, however, the ODST helmet features a distinct, more rounded visor. This version is made of titanium and is coated with a heat-dispersing material; the inside of the helmet is lined with padding to provide comfort for the user. The visor is capable of polarizing, fully obscuring the user's face, or depolarizing, becoming nearly transparent, at the user's whim; the visor is generally colored silver-blue, though red,<ref>'''Halo: Helljumper''', ''[[Halo: Helljumper Issue 2|Issue 2]]''</ref> dark orange,<ref>'''Halo 3'''</ref><ref name="H:R"/><ref>'''Halo: Fall of Reach - Boot Camp''', ''Issue 3'' and ''Issue 4''</ref><ref>'''Halo: Landfall'''</ref> silver,<ref name="H:R"/> black,<ref name="H:R"/> and golden polarization are also possible.<ref name="H:R"/>

The newest version of the helmet links with the wearer's [[neural interface]] and features a head-up display; this HUD provides a targeting reticule, weapon and ammunition information, and a bio sign readouts. It also features thermal imaging equipment and [[motion tracker]]s.<ref name="HE"/> The most remarkable aspect of the ODST helmet is the [[Visual Intelligence System, Reconnaissance]] (VISR), which provides on-the-fly access to [[Unified Earth Government|UEG]], [[Colonial Administration Authority|CAA]], and UNSC databases, as well as enabling the storage up to 610 megabytes of secure data. More significantly, VISR provides the user with access to a dynamic [[TACMAP]] and outlines hostile personnel in red, friendly personnel in green, weapons in blue, and objects of interest in yellow. VISR also provides the user with low-light vision enhancement.

===New Mombasa Police Department model===
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.<ref>'''Halo 3: ODST'''</ref>
