Hello. I can call an Airstrike, giving a range Buff for Towers, healing the Base, dropping Troops, and dropping Nukes. But if i call twice, i can bring Supply Crates which can give Cash, unstun Towers, and heal my Troops. Also if i call three times, it will bring Troops of Paratroopers to drop them down. I have three Troops which are: Paratrooper, Demoman, and Bombo.
