Missiles

From Advance Wars - Wiki on Neoseeker

Missiles are the 2nd Anti Air unit in Advance Wars. The missiles can easily shoot down air units, such as Fighters and T Copters. Like the other indirect combat units, Missles may not fire on the turn they move. Missles are very situational to use, seeing as many maps do not have an airport for either team to use. Still, missles can be useful when fighting COs that specialize in the air such as Waylon and Eagle.
