United States Armed Forces

The United States Armed Forces were the pre-War federal military forces of the United States of America, consisting of five branches: The Army, Navy, US Marines, Air Force, and the Coast Guard.

Background
The country's armed forces participated in numerous wars, including the World War I and the World War II.

The Resource Wars
Amidst an increasingly chaotic and violent international situation, the United States began to militarize. One of the first major projects emerged in 2059, as the Anchorage frontline was established in Alaska to protect the state's natural resources and escalating tensions with Canada, as the United States military units demanded permission to guard the Trans-Alaskan Pipeline by stationing troops on Canadian soil.

The Sino-American War
A year later, in 2060, available fuel reserves were on the brink of depletion worldwide. Traffic on the streets died as fuel became too valuable to waste on cars. The automotive industry desperately tried to come up with a solution to the problem, but electric and early fusion cars were too little, too late to solve the needs of society. The problem was further emphasized by the collapse of the European Commonwealth and the Middle East oil powers, as the oil fields were exhausted. Together with a deteriorating economy and worsening social climate, the United States began to crack. The United States government used the increasing national paranoia to try and control the situation, by discouraging assemblies, fueling the anti-communist sentiment, and encouraging reporting subversive elements. The Vigilant Citizen's Hotline was even established to allow hysterical citizens to report neighbors to the government for any behavior that could be construed as in support of communism. The Third Red Scare is a response to the increased hostility of the People's Republic of China and its operations on American soil.

The military was particularly affected by the fuel shortages, as its vehicle fleets, especially tanks, became crippled by a lack of fuel. In response, the United States Armed Forces initiated a research program seeking to develop power armor in 2065. Research, development, and prototyping pave the way for future advances in military, construction, and most importantly, cold fusion technology. The military would continue research in other areas continues as well, including more powerful nuclear weapons.

The breakthroughs in technology and possession of oil reserves would result in the United States clashing with the People's Republic of China. As the economy of the communist state was dependent to a much greater degree on fossil fuels than that of the U.S., China found itself on the border of collapse in the spring of 2066, with oil fields finally drying up globally. With the United States unwilling to export its own reserves of crude oil, China became more aggressive in its negotiations. According to the Sierra Depot GNN transcript, in June 2074, this resulted in a declaration by the U.S. president that the last known supply of petroleum would be used exclusively by the U.S. and the U.S. would not sell or trade any oil to outside parties. Adding further insult was the first crude fusion cell developed for the power armor project, revealed to the public in summer of 2066.

Desperate to avoid collapse, China launched an invasion of Alaska to seize its natural resources. This daring, trans-Pacific military operation began the Sino-American War, the last war the United States would ever fight. It also inadvertently triggers the gradual annexation of Canada, as the United States forces it to grant the right of passage to American military units on the way to the Alaskan theater. As China is fully committed to the Alaskan operation, United States forces find themselves outmatched and pushed back. The T-45 power armor is rapidly prototyped and pressed into production to prevent Chinese tanks and infantry from overrunning Alaska. The first units prove to be incredibly effective in defense, but somewhat lacking in offensive capabilities. As the Chinese military lost the initiative, the situation rapidly deteriorated into trench warfare as neither side was capable of breaking the stalemate and forcing peace terms on the enemy.

The war consumed increasing amounts of resources, material, and manpower, straining the ailing American economy. To counteract this, the United States military began to liberally exploit Canadian resources. Protests from Ottawa are ignored as Canada became little more than a colony of the United States. Canadian riots and protests eventually culminated in a sabotage attempt on an oil pipeline in 2072. The United States military used the incident as a pretext to invade Canada outright and begin annexation. On the domestic front, the United States Army contracted RobCo Industries and General Atomics International to collaborate on an unprecedented joint project: The creation of the most powerful combat robot in the history of warfare, to liberate Anchorage, Alaska from Chinese occupation in a display of power meant to demoralize the enemy and force them into submission. The project was meant to serve both military and propaganda needs. The former dictated the capacity, the latter the design: In the words of General Constantine Chase, initiator of the project, Liberty Prime was to embody the American military: A walking, talking, nuke-tossing hero reminding enemies of the U.S. that they picked a fight with a global superpower. Confident that the project would soon yield result, General Chase publicly confirmed in June 2072 that the U.S. Army was working with General Atomics and RobCo to create a superweapon meant to establish the dominance of the United States on the Alaskan front.

Furthermore, the aggressive use of biological weapons by the Chinese led the government to order West Tek to develop a Pan-Immunity Virion on September 15, 2073. The research would eventually evolve into the Forced Evolution Virus project. Since West Tek was effectively nationalized two years prior (put under military command), the scientists had no other choice but to obey their military masters.

The economy was stretched to the breaking point as America found itself fighting a war on three fronts: Canada, Alaska, and mainland China. Neither side was willing to yield, despite eight years of constant warfare, and ambitious flanking maneuvers such as the Gobi Campaign.

By 2076, the war had raged for a decade. Both China and the United States teetered on the brink of collapse. In January, a permanent garrison was installed at West Tek, to ensure that the Forced Evolution Virus project remained safe from international espionage, as it entered a new stage of experimentation on dogs and chimpanzees. By the end of the month, the annexation of Canada was completed. Its provinces are put under martial law - all protesters and rioters are shot on sight. Atrocities committed in the name of the Union make their way stateside, fermenting anti-governmental sentiment.

However heinous the annexation, the military gained an advantage to offset the problems with economic strain. The introduction of the T-51 power armor in June helped tip the scales in favor of the U.S. military. The next-generation power armor resolved problems existing in older generations of armor. Mechanized cavalry units outfitted with the T-51bs were sent to the Alaskan and Chinese fronts, carving a swath through Communist forces. The Chinese economy crumbled under the onslaught and supply lines from nations annexed by the Beijing regime started falling apart. However, the American regime did not fare any better. In August, food and energy riots start in urban centers across the United States. A state of emergency and eventually martial law was declared, with U.S. military forces being deployed on the domestic front to fight their own countrymen. The United States became, effectively, a military junta.

Other operations

 * Anchorage Reclamation, an 11-year campaign to liberate Alaska from the Chinese invaders. Ultimately successful, it was the first large-scale deployment of newly developed T-51b power armor units.
 * The annexation of Canada was also performed by the United States military, whose units were also dedicated to keeping the peace―by any means necessary.
 * Veterans of the Anchorage campaign were also deployed against their fellow countrymen, to contain food riots.
 * The Gobi Campaign, that took place in the Gobi Desert. The Gobi Campaign scout rifle was named for this campaign.
 * The Yangtze Campaignd on the island of Mambajao in the Philippines on the eve of the Great War.
 * Fought in World War II from 1941 to 1945.
 * Soldiers/astronauts appear to have been engaged in combat operations on the Moon at some stage prior to the Great War. This is supported by the mural in the Museum of Freedom, which depicts an astronaut with a weapon and the mentioning of the Sea of Tranquility along with other battles.

Army
The United States Army was one of the principal branches involved in projecting American power throughout the Resource Wars and the principal operator of power armor. It was the Army that held the line in Alaska for over a decade and eventually led the decisive push into Anchorage in 2077. Together with the Air Force, the Army also maintained nuclear forces and was responsible for operating the United States arsenal of nuclear weapons through the Commonwealth Defense Administration, The Army military police was also involved in carrying out Executive Order 99066, the internment of Chinese and Chinese-American persons in concentration camps.

Marines
Members of the US Marines participated in war games with other military assets, such as United States Army Rangers, and transported Chinese-American citizens to concentration camps per Executive Order 99066.

Navy
It is known to have supported U.S. military operations during the Anchorage Reclamation (including the unfortunate sinking of USS Ebon Atoll by USS Interference in December 2066 ) and participated in the counter-invasion of the Chinese mainland. Naval fighters were responsible for coastal patrols and defense, as well as recovery of enemy vessels captured near American shores. In certain cases, the Navy would also cooperate with intelligence agencies such as the DIA in counter-espionage operations.

Like other branches of the United States military, the Navy was involved in a number of illicit activities. The foremost of these was domestic surveillance, carried out using black sites like Sugar Grove, where Naval analysts and operatives monitored U.S. citizens for seditious activity. Appalachia was a notable example of what defined sedition: Anything that could affect the war effort, including unionization, anti-automation protests, striking, and of course, the Free States. Those who caught the eye of the Navy faced a fate worse than death: Edgar Aarsen, a union activist, was marked for surveillance in March 2075. A year later, he was abducted ("arrested"), murdered, and his children set up for adoption.

Air Force
The history of the air force is closely intertwined with the general history of the Armed Forces. Together with the Army and the Navy, the Air Force was responsible for maintaining the nuclear arsenal of the United States (primarily bomber-based weapons), as well as aerial warfare in the numerous resource conflicts the United States participated in or outright instigated, including the United States invasion of Mexico of 2052, the Sino-American War (2066–2077), and the United States annexation of Canada.

National Guard
Once the threat of nuclear war was finally realized, the National Guard was deployed en-masse across the country to put in effect the various contingency plans that had been devised in the event of nuclear war, which included civilian evacuations, radiation clean-ups and road checkpoints to maintain order post-War.

Technology
By the time of the Great War, the United States military was the most powerful military in the world, thanks to its overwhelming technological superiority. T-60 power armor, T-51 and the older model, the T-45 provided superb protection and the ability to carry heavy weapons into combat, including rotary cannons usually mounted on gunships or fighters. Power armor units were usually issued to mechanized cavalry formations operating on critical fronts. Low-frequency signals, which can travel far-reaching distances through many geographic obstacles, were used during the Sino-American War to transmit messages to submarines. Other materiel utilized by the Armed Forced included energy weapons, robotics, and military transport vehicles.
