A squadron of Erusean aircraft attack Osean recon squadrons over the Chopinburg region. Mage Squadron is sent to help eliminate the Erusean forces. After the Eruseans are shot down, however, they deploy the Arsenal Bird. After the Osean Skeleton Squadron is shot down, Osea commands the remaining aircraft to retreat.
Osea sends Echo Team to secure air superiority over Fort Grays by shooting down all Eruseans in the airspace. After Echo Team shoots down the Erusean aircraft, a group of MQ-101 UAVs enter the battle. Echo 2 shoots them all down.
Two friendly recon squadrons are attempting to escape a thunderstorm, pursued by UAVs. Spare Squadron is sent to escort them out and shoot down the UAVs. Following their escape, an Su-30SM appears and engages Champ.
