Just a simple question, how can I stop the clone jettrooper from using the detpack? I set up some hint nodes for the units to place mines, but the jettrooper wants to do that with his detpack as well and...kind of kills himself by blowing it up in his face.

This can probably be fixed by a simple "SetClassProperty" or something but I don`t know how to write it.

Do other mine-equipped units use the nodes successfully? For the time being, only give the jet trooper mines and make sure everything works. I can't imagine why detpacks would get placed instead, since they have different class labels.

I think this is actually a glitch in the game itself. You may have noticed the AI doing this with both DetPacks and Time Bombs in the stock game.

There is no fix. Detpack units will simply follow mine units and imitate their behaviour.

Try placing a few cover hint nodes in the area around your mine hint nodes to "distract" the AI from blowing themselves up.
