57mm Valhalla Turret

Thanks to Checkers for the link!

That a BIG setup, but I'm assuming it doesn't penetrate into the cabin.  If that's true then we're seeing something nice.

Check out the Odin 570 here (note the caliber...that's a 57mm gun...naval artillery on a ground vehicle...if we went this way then engaging old tanks would be easy...even new ones could suffer damage)
