First created in 2051, the military-grade combat armor was designed to protect key sections of the human body from ballistic trauma with hard armored plates made from complex polymers and ceramics, with a flexible body suit interwoven with thermal-dissipative membranes and bulletproof material. The earliest models of the combat armor were manufactured as specific plates mounted on combat webbing, although as the technology improved, body-enclosing suits of armor were created and entered active combat duty, though in limited quantities. The armor came with a matte-finish olive drab coloring by default, making it suitable for woodland and/or urban camouflage.
Prior to the Great War, combat armor was nearly exclusively the property of military forces and special police units. Currently-available historical documentation shows users only in the North American continent, but allied nations were likely to posses identical or similar systems. Combat armor was the de facto armor of the United States military, issued to all combat soldiers not in the powered armor units. Additionally, at least one Canadian partisan was caught on camera wearing a suit of combat armor.
Like all versions of combat armor, it was designed to sheath the human body as completely as possible in high durability armor. The primary skin of combat armor is composed of complex polymers and ceramics. This hard armor was manufactured as specific plates, with a matte-finish white coloring suitable for winter camouflage. These plates are affixed to a flexible body suit woven from projectile- and energy-resistant, fire-retardant materials. Like most of the items introduced in Operation: Anchorage, it has two variants - a simulation variant (with 999,400 HP) and a Wasteland variant (with normal HP).
The variant obtained with the Gary 23 glitch does not degrade and under the effects screen, it provides the same statistic bonuses as the T-51b power armor, with the exception of the damage resistance boost.
The winterized combat armor appears inside the Anchorage Reclamation simulation at the Outcast Outpost. You get a set of it at the start of the add-on, plus you will see almost all American infantrymen wearing this.
It is possible to obtain an infinite health (Simulation armor) set through the Gary 23 item glitch along with every other item you had in the simulation.
