Objective: Activate and use one of the turrets to hit the boss, then defeat the boss and activate the other turret

Failure Condition: Boss reaches the enemy Command Center

Recommended Echelon(s): AR/SMG (x2), Dummy

Echelon Limit: 6

For this map, we want to split our two AR echelons up to take care of the turrets that are on opposite sides of the map. First we'll get rid of the left one, then the right one. We'll also want to protect against some of the Nytos roaming about, but it shouldn't be a big deal. Let's begin.

Deploy both of your AR echelons to start. Move the NPC echelon to the left so it takes the Heliport there. Next, move the AR echelon at the bottom Heliport to the left three nodes and take that Heliport. End the turn there.

On turn two, deploy a dummy echelon on the bottom Heliport then swap it with your other AR echelon. Move that AR echelon three nodes to the right to take that Heliport there. Next, move the AR echelon that went to the left all the way up to the turret on that side of the map. Activate it and use it on the boss. This satisfies the first objective of the map and starts the next set of objectives. End the turn. 

On turn three, move the AR echelon on the right up to the right turret and activate it. This should complete one objective. Since we started this second set of objectives, the boss should be chasing your left AR echelon, so you can move to engage her. Killing her will end the map.
