Objective(s): Collect 3 moons, then defeat SCAR-L

Recommended Echelon(s): RF/HG

Echelon Limit: 1 (probably, I didn't write it down, oops)

In this final map, we're tasked with taking down SCAR-L. She's really pissed off so we can't really do that immediately. Before we can engage her, we need to get various moons that spawn on the corners of the map. Once we have three of them, then we can deal with SCAR-L. We do have a little bit of an ace up our sleeve though. SCAR-H is with our echelon (in spirit, or something) and allows us to essentially nuke an enemy echelon if we need to. If I remember correctly, this does have a limit, so don't use it unless you need to. So, let's get started.

On turn one, move your echelon over to the left and grab the EMP. Head up to the moon in the upper right part of the map. We don't really want to grab the moon just yet, as doing so buffs SCAR-L to move twice per turn. So end the turn on top of it.

On turn two, grab the moon then skirt around the Aegises and move to the closed Heliport we have at the middle of the map. Head to the left from that Heliport. This should have most of the Aegises surround us, which is pretty much what we want. 

On turn three, use SCAR-H's skill on the left Aegis and engage it. Keep moving to the left and start heading to one of the moons. I go for the bottom left one in the video. If you have some enemies there, feel free to fight them, but keep an eye on your resources. You won't be able to get to the moon just yet, so end the turn once you've gotten as close as you can.

On turn four, grab the moon. I decide to end the turn after grabbing the moon so I can grab the closed Heliport. You can also start heading to the other moon if you so wish.

On turn five, start moving to the next moon. You should be able to get it on turn six. If a death stack is closing in on you, toss an EMP to stall it. Like I said, you need to watch your resources, so you can't be taking too many battles.

Once you've gotten the last moon, SCAR-L should be fairly close. Use SCAR-H's skill on her and engage her. The fight against SCAR-L is fairly simple. All you need to do is slam SCAR-H's skill in battle repeatedly. Without the three moons you probably can't outpace her pushback. Probably. It might be possible. Don't try it.

Anyway, once you've defeated SCAR-L, the map will be cleared. Good job.
