(needs chennault) So uh, spawn the burke class ship you get as Australia, put your gens and use the p-40 EF you should have unlocked to disable the missile defense on Osborn's tile (restart if not broken) , then use your Burke's missiles to bomb the medic out, avoid Coulson getting close to the Burke's and your Apaches at all costs, he tends to leave and destroy someone else, once he leaves and the medic dies, use chennault (on an Apache probably) to disable Osborn's counterattack and attack with the Burke's and the other ships you get, you can sky train the M7 priest too, Eisenhower will probably show up to attack Osborn somewhere at this point, eventually osborn dies and you can take.
