In retaliation for the "Osean" terrorist attack in Dresdene, the Yuktobanians simultaneously launch an raid on the civilian Apito International Airport and chemical attack on Bana City. The Wardog Squadron, grounded in Oured for hearing, is sent to Apito while the Capital District Air Defense squadron is sent to Bana. After shooting down the enemy fighters, they have to deal with the Yuktobanian forces hidden in the transport planes (mistakenly marked as the Osean Air Force) that landed in the airport earlier. The enemies are destroyed in time and the civilian damage is minimized.
