I could see a nice World War II D-Day thing where you play as a nation on a beach, and have weapons designated to that nation. Or Heck Look up the Winter war! That would be fun. Playing Finnish, and Russians? I could do a modern one with Israeli, Un, NATO and other nation soldiers (Israeli soldiers are awesome.) So long it was realistic. Like the guy who carries an RPK can only be prone, and he can't run. That seems fun. I like faking it for like City, futuristic, but for military I like realism.
