Tyler Island is an island located in southwestern Usea.
During the Lighthouse War in 2019, the island was heavily contested between Osea and Erusea. As the war progressed, the Spare Squadron, now an official squadron, were deployed to retake the northern part of the island, which was under Erusean control.
As they arrived however, the operation was still underway, leaving the squadron stranded on the island. A number of prisoners from an Osean penal unit escaped, stealing multiple aircraft and shooting down their former allies. Avril Mead, Tabloid, and a number of 444th personnel travelled around the island until they came across Princess Rosa Cossette D'Elise's crashed transport, as well as the Princess herself, who was the only survivor of the crash.
On October 10, 2019, the Cyclops and Strider Squadrons were deployed to the island in order to gather supplies from the base. By the time they had arrived, the island was still being contested. By identifying both Osean and Erusean forces, the squadrons successfully destroyed all Erusean Radicals attacking stranded Osean forces. As the operation progressed, Erusean conservatives attempted to carpet bomb the Mass Driver, which would result in several casualties on both sides. The squadrons successfully shot down all bombers. Using a tactical radio they had found, Avril and Tabloid contacted them, requesting assistance for many refugees they had discovered. The Princess later marked the group's position using a flare, and the squadrons quickly destroyed all incoming Erusean forces surrounding them. Immediately after their rescue, the Radicals attempted to launch two supply ships aiming to resupply the Arsenal Bird, both of which were shot down by Cyclops and Strider Squadrons.
Following the operation's success, Avril and the others found a boat and escaped the island.
