Strategy[]
This mission is similar to the previous Chapter mission, Chapter 3: Neighbouring Nations Tremble, but is harder. Any kind of high-level Air, Armor, or GEAR Infantry units will be able to beat this mission. Try to avoid sending in low-level Armor or Infantry units, as A10 Thunderbolts and Avengers have buffs against them.
