Schwarzesmarken also known as Black Marks, is the East German Army 666th TSF Squadron. They are special-forces unit assigned to assault BETA forces using eccentric strategies.
They target Magnus Lux and Lux to prevent BETA from using their ranged firepower advantage. Their orders are given the highest priority which allows them to neglect allied distress call that results in diversion from their planned mission even for a brief moment. Irisdena Bernhard is the squadron commander piloting the MiG-21PF and her squadron utilizes MiG-21s weapons.
