Full Spectrum Warrior began as a training aid for the U.S. Army to reinforce Army doctrine and team effort within the troops. It is the most realistic portrayal of Infantry-level urban warfare via unique tactical action gameplay. The U.S. Army is the most powerful ground force in the entire world. The backbone of a ground invasion is the U.S. Army Infantry, and in the midst of combat, their skills, courage, and teamwork are put to the test. While readiness continues to be the U.S. Army's top priority, how it goes about its business is changing. There is potential for danger down every alley, behind every window; watch those angles folks, we've got a job to do here. Hooah!
