well, technically it has the black skin that MED applies to everything.

I recompiled the level and changed the level_load code somewhat so a wait(5) follows the level_load command. Now all the bodies have a metal flag, but none of the turrets do, even though it is set in the first line of the action.

EDIT: I applied metal to the turret of a nearby panzer (to be used as target practise) and all the metal flags except the body of one tank turned off. I also did a quick front map of each model, and left them black. No change. Only one model has metal turned on, which is dumb b/c the other three tanks have the same exact actions applied.
