no I think it is for recruiding, saw a documentary about it on Discovere, if it's the same game
That's 'sort of' correct
It is actually made by the U.S. Army, they say they don't use it for recruiting, but they use it as a promotional tool (iirc)
I played it myself a few years ago, and they do have a support section on their site:
