Essentially the game production is very similar to any true to life military film. An independant commercial company (in this case Ignited Minds) does all the work and content creation, while the Army provides the needed advice. (Lt. Col. George Juntiff is one of the project advisors)
Here's a quote from an interview: You don't have to worry about being asked to sign up or having your personal information given to the military. "If it leads to recruitment, fine," Juntiff says. "But, again, the idea is just to tell people what the Army is all about. There's no data tracked on you unless you voluntarily go and say, 'I want more.'"
Basicially to me, thats the same as seeing "Saving Private Ryan". I get an insight into the military, with a personal story attached. There is never any point where the movie tries to direct me to a recruitment office, and the same with the games.
The one point that is really different here is the source of funding. Yes, the Army budget is paying for these games. But that dosen't make me think of it as a recruitment tool.
