Objective: Get to the Radar Tower and extract all 3 Ermas

We got a puzzle-ish type map here. There's a lot of enemies and the NPC echelons you're given can realistically only take one fight each. So we need to minimize how many times we fight. Let's get to it.

To start things off, we want to move the top Erma to the right for one battle. Move her up one more node after the fight. Move the middle Erma to where you fought the first enemy. Swap her with the top Erma. End the turn here. We want to manage the Alert AI so it's not disruptive to our later turns, so we don't have any good moves for now.

On turn two, move the damaged Erma to the left for safety. Next, move the Erma that started in the middle to fight the enemy to her right. Then, move the bottom Erma all the way to where the middle Erma was at the start of the turn. Swap the bottom Erma with the now damaged middle Erma, then move her to the right one node. 

On turn three, keep using the bottom Erma to move to the enemy guarding the Radar Tower. Take them out, then proceed to the Radar Tower. Extract her since they're already over there. Move the middle Erma down one node to keep her safe. End the turn there. 

On turn four, move the middle Erma to the Radar Tower and extract her. End the turn.

On turn five, move the last Erma to the Radar Tower to extract her and end the map.
