Copter

Copter (called Heli in Advance Wars: Dark Conflict) is a unit type for helicopter units. Currently two units belong to this category: B Copter and T Copter. Units in the Copter unit type are extremely vulnerable to specialised anti-air weapons (such as Anti-Airs and Fighters) and can also be hit by machine guns and, oddly, Anti-Tanks.

COs who have bonuses tailored to copters include Eagle (increased firepower and defense, reduced fuel consumption), Sensei (increased firepower for B-Copters, increased movement for T-Copters), Tasha, Waylon and Greyfield (increased attack and defense)
