“We took a back to basics approach that highlights a move, shoot, communicate system within a fun gaming experience that echoes teamwork-based Army training,” said Marsha Berry, Project Manager for America’s Army. “Just like in the Army, America’s Army: Proving Grounds focuses on creating elite, well trained Soldiers that will complete the missions as a fine-tuned team beginning with smaller, focused exercises and advancing up to larger, more complex exercises.”

Bringing the best features of the previous versions to a new America’s Army environment, AA: PG stresses small unit tactical maneuvers and training that reflects the current day Army. America’s Army: Proving Grounds (AA: PG) showcases the Army by emphasizing Army Values, teamwork, training and completing the objectives through gameplay that reflects the Soldier’s Creed.
