History
Little information is available about the only female pilot in the Yellow Squadron, Yellow 04. She originally met Yellow 13 as a little girl and he would later train her as a fighter pilot. Some time before the war, the two developed a strong bond. On November 19th, 2004, ISAF's 118th Tactical Fighter Wing attacked the petrochemical refinery complex and oil fence for Erusia's “Invincible” Aegir Fleet that was now immobilized. After arriving into the area after the battle, the Yellow Squadron drove the rest of the ISAF aircraft out of the combat area. Yellow Squadron did manage to shot down approximately three aircraft before the RTB was complete. It is unconfirmed that Yellow 4 did actually fire upon the enemy.

On December 31st, 2004, the Yellow Squadron, along with several other Erusian fighter wings, attacked ISAF Comona Islands Rocket Base. Their objective was to prevent ISAF from launching a reconnaissance satellite. Yellow 13 ordered a retreat during the engagement after one out of the squadron's seven Su-37 Terminators was damaged by an enemy air-to-air missile, the shot actually came from Mobius One.

On April 2nd, 2005, a bomb was planted by the San Salvacion local resistance in the Yellow Squadron's base, knocking out one of the engines of Yellow 4's Su-37. That same day, the ISAF launched an assault on Erusea's valued Stonehenge Turret Network. The squadron launched en-route to STN shortly thereafter, even with Y4's faulty engine. By the time the Yellows had arrived to Stonehenge airspace, it was too late: all of the complex's defense systems & railguns had been destroyed by the ISAF's assault. A fight then broke out between the ISAF aircraft and the Yellows, at which point Mobius One of the ISAF destroyed Yellow 04's Terminator, swiftly ending her life.
