Queen's Gambit IV

*** It is important to be flexible in mission due to Girls Frontline does not have fixed enemy movements. So adopt accordingly.****

Clear Condition: Establish Supply Route and maintain it for 5 turns.
Required Squads: 1 Combat [Night/Armor] + 1 Dummy OR 2nd Combat

This map has bit of RNG where if you only have 1 Combat Echelon, your Supply point can be taken by enemy units and will have to test your luck once more later down the line. However this method is fairly consistent if supply point is not taken at the end of 1st turn.

Combat echelon starts at the HQ and move to take helipad Northwest of HQ.

Combat echelon resupplies then Sweep its way to Supply point. Then swap with dummy unit on helipad.

Just to provide buffer zone for later turns, take out the armor unit that's on radar.

As you can see now that there's two enemy units threatening the supply point. Move up the combat echelon and swap so that dummy echelon is out of harm's way.

Kill the armor unit on the left side that can sever the supply route.

After that you should not see any more units coming from the yellow helipad until end of the mission. Guard the Supply point with your combat echelon.
