America's Army the original one ended up being a terrible game for playability, because it turns out making rifle shooting even semi-realistic is hella boring lol.
Lot of slowly crawling around the map on your belly, calling positions to snipers and grenadiers, and just waiting.
I haven't looked at it in decade++ though, so maybe it's an actual game now.
I don't think AA was ever legitimately meant to find people in that way and was just a more traditional advertisement/propaganda tool meant to feed anyone into the recruiting pipeline.
Ok I looked up the more recent version of the game, apparently it has in fact capitulated to populism and no longer emphasizes realistic tactics. Supposedly many servers will kick you for camping now.
