The LRSSG received a communique from the partially-restored general network, informing them of an Osean-Erusean coalition to destroy Arsenal Bird Justice via a saturation attack. Along with it came a message from members of the 444th Air Base, which read: "Hey dumbass. If you want to bring the world back from the brink, go to the lighthouse. You can see the future there." Motivated to end the war, the LRSSG sortied to participate in the operation.
By the time the LRSSG arrived at the elevator, the battle was in full swing. Thanks to the data link provided by the Osean Army Southern Command HQ, the LRSSG was able to identify and engage hostile fighters alongside Osean and Erusean allies.
Later, Justice launched several salvos of Helios burst missiles in an attempt to thin the coalition's numbers. Regardless, the saturation attack proceeded once Justice entered the vicinity. Unfortunately for the coalition, the Arsenal Bird activated its APS to shield itself from the salvos of missiles.
With the saturation attack a failure, the coalition was forced to conduct separate attacks, which turned against the coalition's favor when the Justice was able to annihilate the coalition's naval component. However, neither the coalition nor the Radicals knew that someone inside the Elevator was sabotaging the panel feeding energy to the Arsenal Bird. The APS eventually failed, allowing the coalition air forces to strike again.
Trigger led the charge, aiming for the vital propellers and--at Wit's suggestion--the rectenna's base. The APS unit inside Justice was eventually destroyed, and the last Arsenal Bird finally went down in flames.
The Erusean Radicals around the space elevator began laying down their arms. However, the late arrival of two highly-maneuverable UAVs inflicted heavy casualties on the coalition air forces. Count's aircraft sustained damage in the UAVs' assault, prompting Trigger to escort him to the OFS Admiral Andersen, a beached Osean carrier.
