Mission and Clear Conditions:
Hold Supply Line for 3 Turns (Main Route to "A New Hope")
Defend for 7 Turns (Side Route)
2 Combat Echelons. 1 RF/HG, 1 Capable of killing Typhons. Gunboat recommended, M4/MG comp can work in a pinch
2 Dummy Echelons
Included below is an example of an M4A1/MG gunboat.
This map is similar to 3-4A, although with a few less nodes. Just like that map, a Gunboat, or similar Echelon is recommended to handle the Typhons on the right side of the map. Besides the Typhons, the enemies present here are heavily armored, so RF/HG Echelons are a must. In spite of appearances, establishing the Supply Line is quite straight forwards, one should simply remember to take advantage of encircling mechanics, and mind their micro to limit incoming damage. Outside of those few challenges, this map will be over in a snap.
Deploy a Combat Echelon on the Heliport and Command Post. Move the Command Post Echelon to the right one node, and down one node.
Move the other Combat Echelon down two nodes.
Deploy a Dummy Echelon on the Command Post, and the newly capture Heliport. Both of these should be HGs.
Move the Typhon killing Echelon right two nodes, and down two nodes.
Move the right Dummy Echelon down, right two nodes, and down again.
Move the Typhon Killing Echelon down one node.
Move the right Dummy Echelon back up one node.
Move the left Combat Echelon down three nodes, and then right onto the Supply Point.
Retreat and Redeploy the Echelon on the Supply Point. Move them down two nodes, left, down, two nodes, and right back onto the Supply Point to finish out the map.
Survive 7 Turns
Deploy a Combat Echelon on the Command Post. End turn 7 times. Profit.
