I dread having to redo that mission...only thing I can think of is trying to use the waypoint thingy to force them to walk along with you.
Didn't work. They ran to the way point and then back and then to and then back. Over and over again.
That mission gave me nightmares for that very reason. Eventually I started luring bad guys back to where my officers kept getting stuck so my guys would actually contribute to the mission. Aargh.
Also didn't work. They just ran around ignoring the Cardassians.
That entire mission should be blown up.
