de-pbo it so you have all the file to view. Then open the config.cpp and look along the lines of:
class HatchDriver
{
selection="poklop_driver";
axis="osa_poklop_driver";
angle=110;
};
class HatchCommander
{
selection="poklop_commander";
axis="osa_poklop_commander";
angle=115;
};
class HatchGunner
{
selection="poklop_gunner";
axis="osa_poklop_gunner";
angle=115;
   };
  Â
well delete these lines and hey presto you have a tank with no turn out animis
