Recommended Echelon(s): AR/SMG (x2)
Your transition chapter. A relatively simple map to ease you into the difficulty of chapter 3. Elimination doesn't require any particular strategies during the day, especially with no turn limit. I will say your main goal should be to hold the middle triangle of heliports, as there's a lot of enemy movement through there.
The big thing in this map to be aware of is the black Golyats. They come in pairs in battles and if you lack firepower, you can very easily be slapped with a 9999 to all your T-Dolls. Be sure to retreat if needed, or repair if you do get hit.
