It was issued primarily to Enclave troops operating on the United States mainland. Additionally, like the T-51b power armor, it includes a recycling system that can convert human waste into drinkable water, enhancing survival and an air conditioning system for comfort. The suit has an auto-gyro system to keep it upright and the knees can be locked in position, to prevent the wearer from falling over if, for some reason, he loses consciousness on duty. The motion-assist servo-motors used in the armor appear to be high-quality models as well, giving the wearer a +1 Strength bonus. It is composed of lightweight metal alloys, reinforced with ceramic castings at key stress points. Various accidents, explosions, and deaths were involved in its creation but were classified by order of the Enclave's President Dick Richardson for the sake of morale. In 2215 the first truly superior suit was manufactured, entering service in 2220. The armor was created by the Enclave's skilled team of engineers and scientists after the Great War as a result of a research program initiated in 2198, part of a larger project to develop various technologies.
