A note of interest for any tankers. I have found that the T-55 listed below, seems to work very good.
The only issue I have found so far is that the commanders weapon cupola does not fire or traverse. But the main gun and GPMG work fine.
Everything sounds OK as well.
EDIT- The T-55 listed above works fine as long as you place it as "EMPTY" in the editor. Arma II does NOT recognize the crew. Just the tank.
