Could be a problem if any of em bite the bullet...but yeah that's what I meant with the AI movements...it's hard-coded into the setup action.
If any of the guys are hit, and you are already stay up, then you could remove the action "break down MG" - you'd need to use it to be able to move again. So, if any of yer dudes die, then you're stuck in one place...unless you feel adventerous enough to come up with a script that lets you "draft" a new loader from the surrounding men...
