Objective: Rescue and extract 3 hostages.
Turn Limit: It's a one turn it literally doesn't matter.
Echelon Limit: 1
Recommended Echelon(s): Dummy

This map has no combat whatsoever. All you do is use a dummy to get to a hostage, swap with them, and extract them. You do this on each hostage and with how much AP you start with you can do this in one turn.
