Mission and Clear Conditions:
Defeat every Enemy in 4 turns
- 2 ARSMG (DPS ARs Recommended against large amounts of Orthrus)
- 0-1 Dummy
- 1 HOC (2B/AGS/M2)
- Strong SF if needed
Move the ARSMG Echelon up-left one node.
Deploy another ARSMG Echelon on the Command Post and move it down-left one node, switching with your HOC, then move the upper RFHG Echelon up-right two nodes.
Move your 1st ARSMG Echelon down-left one node, after that move your 2nd ARSMG Echelon up one node, switching with your HOC and then down-right one node.
Move your 2nd ARSMG down once more.
End your turn.
Deploy a Dummy or another Combat Echelon if you need.
Move your 2nd ARSMG Echelon up two nodes and then down-left three nodes, switching through your other Echelons.
Move your RFHG Echelon on the Heavy Heliport up one node, up-left two nodes and then up right. (or any Echelon in range that can still fight armored Enemies)
End your turn to beat the Mission.
There is a little bit of RNG here, if the last Enemies moved to other nodes, just go there and defeat them, other than that you have 1 more turn for the S-Rank, so don’t worry, you can defeat them on the next turn if needed.
You can also watch the Clear video as an example of what to do.
