For shits and giggles, try
vectorUp or one of the other associated vector-commands. Since it DOES tilt one would think it might even change vectors or somesuch in there, no?
Secondly, once again for shits and giggles, you could try the animation commands on the UNIT performing the action - once in a blue moon BIS will have given the animation to do something a unique name and entry, while the actual animation played is still the usual "bend down and tie your shoelaces" one. By using that around mines in some kind of watching script, you might be able to see if the mines have been deactivated or not?
And finally, take a good look at
this beauty - it can among other things return the number of active mines in the minefield, so if nothing else you can pick it apart and figure out how he did it, or simply use it as it is for your mission!
Wolfrug out.
