MP-class Mjolnir

The Mark V[MP] is a UNSC Military Police helmet adapted for use with the Mark V MJOLNIR Powered Assault Armor.

Description
One of just a handful of assets shared between branches of the UNSC armed forces, the MP variant is a shared asset with Beta-5 Security; as such, sensor upgrades are many and varied. The MP variant also includes a "Base Security" chest armor, which is an additional plate of armor placed on the standard Mark V chest, and a grenade belt along the waist.

At least two MJOLNIR upgrades are available for MP users; the External Command Network Module or "CNM" on the left side of the helmet, standard issue for Inner Colony Beta-5 security units, and the Hardened External Sensor Array-External or "HESA-E", which is standard issue for Outer Colony Beta-5 security units.

The MP helmet also serves as the fully enclosed variant of the UNSC Marine Corps and Army helmets - the soldiers who aid the player boarding the Covenant corvette Ardent Prayer on the level Long Night of Solace in Halo: Reach have MP helmets with transparent visors, as part of their vacuum suits. The Marines encountered on the level The Pillar of Autumn also wear similar helmets with transparent visors.
