When you drive the Panther or Kamysh (edit: any tracked vehicle) in reverse they turn left when you press right and turn right when you press left.
edit (18.09.2013):
Every tracked vehicle in the game is affected. Because of that I changed the report title
IF anybody dowvote this ticket, they should know that the tracked vehicles work diferent than the wheeled one, and the tracked vehicles shouldn't have inversed driving controls when going backwards
Everything works like they should work. Tracked vehicles operate differently than wheeled vehicles.
The controls are not inverted when reversing: when you drive tracked vehicle and you reverse & steer right, you're turning the vehicle to right. Wheeled vehicles have inverted controls when reversing (as they should have).
I never drove a tracked vehicle in real life but my understanding is that when i steer to my right hand side, the right track gets slower then the left one resulting in a turn to the right (while i drive forward). When i drive backwards and steer to my right hand side, again the right track gets slower then the left one resulting in a turn to the right side of the vehicle (left side regarding to the driving direction). But the opposite happens ingame.
