Im playing RO for quite long time. And I have some issues with killing tank drivers (when hatch is open). Its happens in a lots of cases... Eg. Im crawling near enemy tank (t34) from he's left side, then driver open he's hatch, im maybe 5 (or less) feet away from him, starting to aim with pistol (or rifle), he's head is excacly in my ironsight (to be more precisly he's head is 3x bigger than my iron sight) and BAM BAM BAM BAM... nothing happens... he's still alive, then tank turn and mg kills me... the same story with commander popping out of he's hatch, im aimng with rifle in the middle of his back BAM, and nothing... can some1 explain this to me? why models are so inaccurate?
