You can blow the tires off, there was a video somewhere where the US truck was driving without one. Don't think it was a bug
. Also RPG/cannon hit on back of the tank or rear side armor damages the tanks engine or something that affects mobility.
Wonder if you can do that to attack choppers. You know few good 12.7mm hits on engine block and it flies slower etc.
Have to say the graphics are amazing, it really does look a lot better than BF3. All the effects mainly.
EDIT: WHAT?! 1.07 one the video posted, does it say RPG-7V2 is homing missile
