When 7.0 came out I took a few tanks out for a spin - starting with the ARL. It seemed like the gun recoil mechanic wasn't turned on - but that's because the ARL evidently doesn't have a recoiling gun. I am guessing it did not in real life either? Also, the T57 gun barely recoils at all. I suspect WG has done their homework on this aspect of the tanks. Yes, it's just a game, but it imports some of these historical aspects of these vehicles.
Cool stuff.
