As is the usual with many war based FPS games the Army helped by recording gun noises, allowing photo shoots or army equipment, and consulting on the campaign. They want to make it clear now though that they were unaware of the inclusion of Taliban as playable until the multiplayer was shown at E3. There are some quote from Kenneth Hawes, director of the U.S. Army’s Public Affairs Office Western Region where he states that upon learning of the situation he “immediately contacted Electronic Arts and asked them to give us a demonstration of the game’s capabilities,”. They were concerned about the issue and wanted to know exactly what they were dealing with.
Hawes and the Army at one time were considering removing support from the game to show their dissapointment. It would have had no bearing on the actual end product but, it was to show that they did not approve.
The playable Taliban were removed from the game before this statement and the U.S Army wanted to ensure that they had nothing to do with the decision.
