Actually there are a few games by the same name:
1. developped by the U.S. army
America's Army (also known as AA or Army Game Project) is a tactical multiplayer first-person shooter owned by the United States Government and released as a global public relations initiative to help with U.S. Army recruitment.
On November 6, 2003, version 2.0 of America's Army was published, with the full title of America's Army: Special Forces. In a booklet produced by the MOVES Institute, an article by Wagner James Au explains that "the Department of Defense want[ed] to double the number of Special Forces soldiers, so essential [had they proven] in Afghanistan and northern Iraq; consequently, orders [had] trickled down the chain of command and found application in the current release of America's Army."[10]
