The Circum Pacific War started with Yuktobania attacking Osea. After their crushing defeat at Sand Island AFB, Yuktobania stopped all attacks. In late October, the 108th Tactical Fighter Squadron was sent on a patrol mission to Akerson Hill in coastal Osean soil, guarding northern Akerson which was out of the local Osean AA automated defense network. However, they encountered a lone Osean C-5B Galaxy en-route to North Point of the Usean Continent which wasn't emitting a friendly signal due to it's flight's top-secret nature, which led to the ship being fired upon by the local AA network, which knocked out its radar. After leading the Galaxy, callsign Mother Goose One, through the AA field, Wardog assisted in its crash-landing in northern Akerson, only to be "rescued" by the 8492nd Squadron.
The Osean Maritime Defense Force sent landing craft to deploy four armored companies of the Osean Marine Corps to the beach. They came under fire even before making landfall. The OADF 108th Tactical Fighter Squadron "Wardog" provided close air support.
Once making landfall, the OMC companies pushed through the mountainous terrain, knocking out several bunkers with Wardog's help. After pushing through the bunkers, the four companies joined into two units who attacked the outer walls of the fortress at the rear. With Wardog's help, they broke through, and joined into one unit to finish off the Yukes inside the fortress' inner wall. With the help of Wardog, the Yukes were defeated, and Osea claimed a foothold in Yuktobania.
Following the successful operation, Osean forces established their GHQ (General Headquarters) on Bastok. From this point on, they would begin pushing towards northern Yuktobania, ever onward towards the capital city of Cinigrad
