America's Army: Proving Grounds hits your PC August 29 - trailer inside

The latest and possibly greatest edition of America's Army, dubbed Proving Grounds, will be arriving on Steam August 29. If you're not familiar with the only video game franchise made by the actual US military, you should know it's free and, uh, different from Call of Duty or Battlefield. But it's free. Trailer below.

Since that trailer provides pretty much no information about what it's like to play it, here's what the AA people say you can expect from Proving Grounds:

"In the game, players will experience the type of positional tactical training that U.S. Soldiers encounter at a real Army MOUT (military operations on urban terrain) site. Set in a fictional country, The Republic of the Ostregals, players are in the role of an 11B Infantryman practicing combat maneuvers at JTC Griffin, a fabricated training environment created by Conex modular containers and found materials. This training is crucial to the player’s success as part of a Long Range Combined Arms – Recon (LRCA-R) unit, a full spectrum capable team that embarks on special operations missions behind enemy lines."
