Oberstleutnant Heinze Axmann, also known as the Brown Beast, is one of the main antagonists of Schwarzesmarken. As the ambitious commander of the Stasi TSF Guard Force, Axmann shared an uneasy relationship with his subordinate and mentee, Beatrix Brehmer. Axmann's cruelty and sadism were legendary even by Stasi standards. He is personally responsible for the atrocities some of the members of the 666th Squadron experienced when they ran in with the Stasi, including torturing Theodor, brainwashing Lise, and forcing Irisdina to kill her brother.
