M52B body armor

M52B body armor is an armored protective vest worn by members of the UNSC Marine Corps. M52B body armor is usually worn with the CH252 helmet for greater ballistic protection. It is the third iteration of the M52 body armor.
== Overview ==
The M52B body armor system weighs 6.58 kilograms and features a heavy chestplate with a layered surface and buckled straps running over the user's trapezius to secure it against the backplate, along with connectors under the arms. An additional buckle is located centrally on the bottom of the chestplate, and the chestplate and backplate are worn over a black under-armor vest which covers the entire torso and runs partially down the upper-arms. The arm coverage of the vest extends only over the outwards-facing portion of the arm, is strapped over the underside, and features integrated pauldron assemblies. Below the pauldrons on each side small shapes extrude from the black material, textured by a number of circular cut-outs. The M52B features a prominent protective collar around the side and back of the neck. It lacks the abdominal plate of the M52A, instead sporting a raised, brown-coloured patch of additional material over the stomach which tapers into groin protection, and a flat-topped discoloured plate at the bottom of the back with two attachment loops on it.
== History ==
The M52B entered service during the 2530s, phasing out the older M52A which had been in use since the 2490s.
