United States Armed Forces

The United States Armed Forces were the overall unified military forces of the United States before the Great War, composed of the United States Army, United States Marine Corps, United States Navy, United States Coast Guard, and United States Air Force. The President served as the Commander-in-chief of the military, with the Secretary of War, Department of War acting as the principal organ by which military policy was carried out.

After the Great War, the Enclave military forces are their direct descendant. The Brotherhood of Steel, on the other hand, was started by former US soldiers that rebelled against their unethical orders.

Before the War
By 2077, the US Armed Forces were the world's most powerful military force. The only rival was the People's Liberation Army of China, with which the Armed Forces clashed during the Sino-American War, in Anchorage and beyond.

The Army was primarily using energy weapons (laser and plasma) in the field, although due to slow production rates, many troops, in particular on the Anchorage Front Line, were still using regular firearms (such as the R91 Assault Rifle). Regular infantrymen, regardless of specialization, wore polymer combat armor (Anchorage troops used special winterized versions), while suits of power armor were reserved for Mechanized Cavalry units and special detachments (e.g. Colonel Spindel's group at Mariposa).

In a supportive role, the Army deployed robots - Sentry Bots and combat versions of the popular Mr Handy - Mr Gutsies. Aerial support was to be provided by next generation helicopters, the VB-02 Vertibirds, though they were scheduled to enter service in 2083, prototypes did see combat at Anchorage.

Fighter support was common and many patrolled the US coastline.

Notable operations

 * By far the most notable operation is the Anchorage Reclamation, an 11 year camapign 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.

After the War
With the nuclear holocaust of 2077 and the dissolution of the chain of command, the US Armed Forces effectively ceased to exist, becoming groups of isolated soldiers with no coordination. Two groups, the Enclave and the Brotherhood of Steel are known to be direct descendant (or include descendants of) the original United States Armed Forces.

However, by 2277, the only reminder that there once was a proud army are military bases scattered across the United States, together with their vehicles and equipment.
