If you are the Commander and turn out of hatch, you can not give any orders to move via W, A, S and D (Slow, Forward, Fast, Left, Right and Reverse)! [All Tank, Howitzer and APC with FFV]
Also you are unable to change the Firemode (MG or Cannon). CTRL+F or the Order via the Firegroups did not work! [All Tank, Howitzer and APC with FFV]
Seems to be connected with FFV... With the T-100 Varsuk it works fine for me!
The order "FIRE" did not work if you turn out (CTRL+Left Click). [All Tank, Howitzer and APC with and without FFV]
