Up to mission 8 now. This really is very good, especially when, like on mission 6, I completely obliterated the enemy using a million tanks and light artillery, finishing the mission without losing a single unit and with full health. Aces!
Mission 7 was a “stay alive for X rounds” mission, and the first to have enemy aircraft. My advisor recommended I use anti-air units, but they were really underpowered and could be destroyed by a gunship in one turn. Heavy infantry was the way to go!
