Now that our mainland division ground forces have successfully retreated from Saint Noah, we can build up our forces to launch a counter-attack. However, the Posrusts are building up an invasion force themselves. Our surveillance has confirmed that a large platoon of bombers, fighters and various ground forces are converging in the Ertuno Desert. We are going to launch a secret attack against these forces so that they cannot converge to attack the Vincent Republic. Your mission is to attack the bombers and other air forces at Balamew Airbase, in the Ertuno Desert.
