Prevent Reloading

[Kilo]

Hi guys!

I've been playing around with the ME and I'm wondering: Is there any way to prevent ground units from reloading after expending their ammunition? Right now I'm trying to make a rocket artillery unit perform a shoot and scoot mission. The group consists of the MRLS launchers, some security and command/comms vehicles and supply trucks, for the sake of realism. The trouble is that, after expending the ammunition, instead of leaving, the rocket launchers wait around to reload.

Is there any way to stop the reloading even when supply trucks are around?
