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.
Unlike the reinforced variants common on the West Coast, all the combat armor available in the Capital Wasteland is short-sleeved, having only the shoulder pads and chest plates covering the torso, as well as the forearm guards. The combat helmet's shaded visor is also absent. The winterized combat armor variant looks the most like combat armor present in earlier Fallout titles, except for the snow-appropriate camouflage pattern and face-covering balaclava.
The helmet is olive drab-colored and its shape resembles the current day PASGT (Personnel Armor System for Ground Troops) Kevlar helmets. The picture shown in the Pip-Boy is also very similar to the German Stahlhelm. Unlike its predecessor from Fallout and Fallout 2, the helmet does not have the acrylic cover over the eyes, so it can be worn with normal eyewear, such as eyeglasses.
↑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
