So, I worked on this. I built their in game support system (irc backed!), wrote a bunch of the web auth code, and accidentally once deleted the production user database from the secondary site (whew, disabled and re-replicated from primary).
It was a lot of fun and got me a trip to E3 back when it was the big thing.
It was an interesting concept because no matter what, you would play the american side and fight the terrorists. (you would look like a terrorist to the other team)
I recall they lowered guys out of a helicopter on ropes one year, too. It was hilarious to walk around the floor at E3 and see CoD or whatever guys in their fakey-looking booth bro costumes pass real army guys wearing real uniforms passing out enlistment info and ads for America's Army. Why pay booth bros when you can just assign some soldiers you're already paying?
I just want to say, your work on that game absolutely would've contributed to making my high-school years better. Me and my social group played this game constantly, spent tons of hours playing SF Refinery 😂 From the bottom of my heart, thank you so much!!
