No echelon changes. I did use a dummy echelon here, though. Keep in mind, this is one of the insanely large maps, so you want as many echelons as possible for this one.

With the mess of 2-4 out of the way, we're back in maps that don't make me want to die. Unfortunately, things do just keep getting harder going into chapter 3. At least 3-1 eases you into it, enemy CE isn't quite up into super difficult territories. However, you're starting to be pressed to deploy more and more echelons. Best be ready to field around 4 echelons for 3-2! Also be ready to do even more night battles with those echelons as well, since chapter 3 is mixed between night and day battles.

Okay, so we have the absolute worst map in this game. Yeah, I hate this map. A lot. It's a pile of RNG garbage due to red golyats roaming around the map blocking your way if you're not prepared to cut through them. To top it off, you have absolutely nowhere to resupply, so you can actually completely run out of resources before getting to the ending heliports. However, smart play and careful movement can let you deal with those. Just to make it extra clear: RNG can affect you, but it will never be the sole reason you screw up the map. What it does it make it so you cannot just mindlessly go through the map and have to actually think about your actions, which is annoying.

No changes. I do use a dummy echelon for this though.

Nothing changed. You can do this with a dummy echelon instead of a second real echelon. 

Chapter 2 starts off as a slight increase in difficulty, enemy power wise. However, overall they're still pretty easy. Except 2-4. Fuck 2-4. Oh, and all of the maps are at night. Fun.

No changes.

I do use a dummy echelon for this. No other changes. 

Nothing changed for this map.

Operation deep dive, the second real major operation (Cube doesn't count, I swear). We're looking at three chapters and 4 maps per chapter worth of brand new content. It also features the second ranking map, in which you'll be assailed by the bosses of the operation, plus some extras while defending a supply route to your HQ! All for a grand prize of a unique equipment for 9A91. Yes, you do want to get that.
