An East German TSF squadron, the 666th or "Schwarzesmarken", enter the fight against the BETA with their Comrade Captain, Irisdina Bernhard. Pilot Anett Hosenfield suffers a nervous breakdown and, in the chaos it creates, pilot Inghild Bronikowski is mortally wounded. Irisdina administers a coup de grace rather than leave Inghild to die on the battlefield. She castigates Second Lieutenant Theodor Eberbach for failing to help Annett, and assigns him to continue the mission while Inghild's body is recovered.

The rebels take over Berlin's broadcast tower and escort Katia inside. The 666th and the rebels engage Werewolf squadron over the streets of Berlin. During the battle, they hear Katia's speech, revealing herself to the nation as Usula Strachwitz, and appealing for the people to rise up against the Stasi.
