Lets get some real tank killers in the game like the JagdPather the Panzer IV/70 or Jagdtiger. I would even settle for a Sturmgeschultz IV or the sd.Kfz 142 Stug & Jagdpanzer 38 Hetzer. Even the Stug III G 75mm assault gun would be great. Anyone with a good throwing arm and a larger rock can knock the turret out of the M-18. Lets get a mans tank killer in here. while we are at it lets put the correct 360% turning MGs back on the German rides. I have personally saw the ring mounts on Tigers & Panthers at the Patton museum and the MGs came with an anti aircraft ring sight as part of the TO&E. Even the Infantry had a tripod MG stand and it too had a aircraft ring sight issued with it. Like my old man always said" If you are going to do something do it right.

Did you forgot to take your meds this morning? Settle down, else you'll soil your drawers.

A "real" tank destroyer? I'm sorry if your M18 bas been damaged by a rock tossing Neanderthal, but I think you're missing the point of the M18. It was one of the best tank destroyers in WWII. You mention the StG III and its 7.5cm gun, mind you it is the same exact thing as AH's current Panzer IV H but the StG has a far less field of fire. Same goes for the Hetzer. Now the Jagdtiger, Panzer IV/70, etc, they might be alright. Ditto goes for the Su-100.
As far as the MG rings on the turrets of German tanks, as yourself *how* a TC fires those MG's when he is incapable of pivoting around the gun mount like the TC's on the Shermans are able to do. The shooter on the M4's MG's usually get out of the turret to use them while the shooter in the German tanks stay in the turret. Yes?
