United States Army

The United States Army or Department of the Army was a contingent of the United States of America armed forces.

Background
Candidates achieved the rank of private once successfully completing basic training at locations such as Fort McClintock. Joined by Marines, training exercises were conducted in the form of war games.

Anchorage
The Chinese army invaded Alaska in the winter of 2066. After ten years of occupation, American Army forces launched an offensive in Anchorage that successfully liberated the city on January 10, 2077.

Domestic activity
Beginning August 1, 2077, the 104th Infantry Regiment's Echo Company was responsible for staffing the South Boston military checkpoint, performing vehicle inspections and detaining passengers as applicable. Members of the US Army Reserve under the 708th Infantry Division were deployed to assist the Boston Police Department with food distribution. The 184th Infantry Regiment was deployed to Boston's Roxbury neighborhood to maintain order at a food bank. Violence erupted and soldiers of the regiment opened fire on civilians, killing four and wounding eight others.

A prototype military transport vehicle developed by the military was displayed at the Museum of Technology at the time of the war. The M199 assault rifle was the official infantry weapon, and the Mister Gutsy model of robot was commissioned by the army. Assaultron robots were constructed by RobCo and sold to the U.S. military as a frontline wartime combatant.

Post-War
The 121st Infantry Platoon, nicknamed Firebats, was deployed to Monongah Power Plant after the Great War to protect the power plant from invasion.
