Sounds like you want an excuse to buy the GW. Okay, if you buy it, I'll buy the ring mount off you. As for the LAV yes they are 8wd with the front 4 steer, but you can switch to 4wd in the rear only for on road use. As for the turret it is very different than the BFV, most notably the armor, but the whole sighting thing too. The sidesaddle TOW missle is a BFV thing. Versions of it have been looked at on the LAV, but the version the Marines use has to swim too and weight becomes an issue. I am out of LAVs now, but maybe the next generation will have something. We currently use a dedicated TOW version that has a big launcher that raises up and shoots.
