Modeled after the human silhouette, combat armors were designed to provide balanced protection without limiting user mobility. They are a diverse family of personal body armor with varying degrees of sophistication, ranging from the earliest iterations developed by the United States Army to the cutting-edge riot gears that came into use prior to the Great War.
Combat armor is the epitome of non-powered armor in the wastes, and was much favored by police and military forces for their outstanding durability coupled with their high level of maneuverability. The armor itself consists of a large chest plate and helmet constructed out of high-level defensive polymers. It is highly effective armor for medium level player characters, as it provides good resistance against small arms fire, laser beams and blasts of plasma energy alike.
In Fallout 2, Combat armor also grants the wearer +20% Radiation Resistance. This is not documented anywhere in or out of the game.
↑The Army helmet is presented in the game as an older type of helmet, issued to uniformed troops who do not use the standard set of combat armor: Clearly visible in the tutorial segment and later on countless dead bodies throughout the Commonwealth.
