Powered combat infantry armor, commonly referred to as power armor, is an unique combat technology developed by the United States defense contractors. It represents the pinnacle of personal defensive technology, combining excellent protection from small arms to any with the ability to carry heavy weapons into combat with ease. Know it is known in the futuristic dimension where it can rival there armor known as IS know it's a clash of supremacy of the better weapon systems.

(The T-51 is the pinnacle of Power Armor Technology Known to man)
Backstory
With the Oil crisis severely limiting the ability of the United States military to deploy combat vehicles, especially tanks and other types of armor, it began research efforts to create self-powered combat suits in August 2033. Mechanized cavalry units provided with them would retain the mobility of a soldier moving on foot while giving them the ability to use heavy weapons with ease. Research proceeded rapidly. While early prototypes were unsuccessful, lessons learned in the process paved the way for future advances in military sciences, construction, and fusion technology.

The most important achievement of this early stage of research was the development of a fusion cell. Crude, but effective, the design was unveiled to the world in the summer of 2044. Most countries ask the American Government to share their technology and refusal to comply as the communist forces try to invade America beginning the Commu-American War which ended in 10 days when the Communist were pushed back by Power Armor not stopping by the slightest of bullets from all calibers, missiles bounced off the armor as they are unable to stop the menacing walking tanks and after the fight they fled in shame and embarrassment by the sheer force the armor created by there enemy spark fear in most countries who didn't want to face the weapon.

The United States Power Increased and no Country ever bother them due to the fear what would happen if they do.

Feats & features

(The variants & Frames)
All power armor models in the United States share a common heritage and basic design. Each power armor is built around the West Tek power armor frame with an internalized servomotor system, providing increased strength, resistance to trauma, and radiation protection. The operator controls the armor indirectly, using manipulators that steer the hands and feet, while being safely isolated from the environment. Of note is integrated hydraulic shock absorbtion system which allows the operator to jump from major heights without damage. The safety of airborne deployments depends primarily on the model of the armor, with the survivable height for early T-60 models being about one hundred feet, increased to more than three times the height in later iterations.

Naturally, the enhanced strength also allows the use of hard armored plating that would otherwise be impossible for the soldier to carry with ease. The basic version of each power armor is designated model A - the letter is usually omitted in this case - with subsequent revisions and upgrades distinguished using sequential letters: B, C, D, E, and F. Each represents an incremental upgrade over the preceding model. Beyond general revisions, a large number of upgrades and custom internals has been developed for the various power armor units, to increase their flexibility and performance on the battlefield.

The power necessary for the unit to operate autonomously comes from a fusion power plant integrated into the chassis of the suit, typically loaded on the factory floor with fuel to last a hundred years of moderate use. Salvaging power armor is also difficult, as the amount of firepower necessary to accomplish this feat renders the armor useless.

T-45
The T-45 powered combat infantry armor are one of the earliest designs pressed into service , with its first deployments taking place in combat. The speed at which it had to be deployed, less than two years after the development of power armor began, resulted in the creation of a stop-gap model utilizing existing technologies and manufacturing techniques. This temporary solution would eventually become the mainstay of American power armor units, especially as subsequent upgrades reduced the impact of the mobility problems that plagued the early production runs.

T-51
The T-51 is the apex of powered combat infantry development. Developed over a decade by West-Tek, it incorporates many of the lessons gleaned from the T-45 power armor service history. Unlike its predecessor, the T-51b benefits from a long development cycle and uses custom-made components to create not a stop-gap model, but a weapon that provides the best possible protection through incorporating the latest passive defense features.

T-60
The T-60 series of powered combat infantry armor is an evolution of the T-45 power armor design. This stop-gap model was extensively modified and effectively reimagined, leading the United States military to reclassify it from an upgrade to a separate power armor variant. Entering service after the conclusion of the Battle of Anchorage, the T-60 is used extensively by the Army alongside the T-51 power armor, including the domestic front, enforcing order of the law.

X-01 (only for officers higher ranking no one else)
The development of the first suit of advanced power armor, designated X-01, began shortly with the first test run issued to Presidential bodyguards.

The X-01 advanced powered infantry combat armor is designed for a single human operator, provided with the comfort and protection of a next-generation suit of armor. While the T-51 power armor relied on a lightweight poly-laminate composite shell for protection, the advanced model uses lightweight metal alloys as basis, reinforced with ceramic castings at key points. The resulting space savings allowed for reducing the armor's profile without compromising protection. Classic power armor pauldrons were retired in favor of a hump that encloses the operator's head, significantly reducing the chance of enemy fire damaging the vital areas surrounding the head. Perhaps the most noticeable change was a completely new helmet assembly. The unusal, insect-like design features a pair of polarized eyepieces in place of the usual vision slit, providing superior battlefield awareness. Its angled surfaces also help maximize the chance of outright deflecting projectiles and incoming fire.

The basic hydraulics system and servo-motors that provide the operator with enhanced strength are also high quality models, with improved performance as opposed to the original T-51b. Additional features include an auto-gyro and the ability to lock them in position, allowing the suit to be stored upright (or the operator to take a nap while on guard duty), an air conditioning system for comfort,a radio headset , and an urine-recycling system carried over from the T-51b, allowing the operator to survive for weeks without water.

Fusion core

Standardized fusion cores are a high-grade, long-term nuclear battery used for military and commercial applications .Used by civilians to power generators,the military instead used them for supplying power armor and some Gatling laser models with energy. Standard core interfaces were developed across the board to allow for power armor frames to use cores.

Power armor runs on fusion cores. Performing any of the following actions will reduce a core's charge:

Running
Sprinting
Power Attacks
V.A.T.S.
Jet packs

Known to man as they can run for hours on end till it runs out and the suit will unable to function as usual of course.

Brotherhood of Steel Academy

(Enlist for the Brotherhood)
A large giant military academy dedicated for training young men to be the best Power Armor Users known to man, which only men can join as the teachers are mostly former Veterans, Officers or Testers of the Weapon, The School is very secretive and is held inside protected by a barrier of course from anything try to harm them.

The Faculty have a near Futuristic retro style Environment that contains the following things from a Court Yard, Mess-hall, Classrooms, training faculty & the Power Armor room where some soldiers have the privileged to modify there armor with the extent of whatever desires of course.

The Academy rival the IS academy school which both sides are curious with the opposite sex of course as the other Said is use to see girls on Magazines, Or contact with them of course.
