Detlef Fleisher was an ace pilot of the Belkan Air Force. He joined the BAF in the 80s, later becoming one of the Belkan Federation's most famous ace pilots.
Detlef was born in the city of Dinsmark in 1967. After graduating from high school, he decided to join the Shainder Academy, thus starting his career in the military. Following his graduation from the Academy, he joined the Belkan Air Force, mainly thanks to the efforts of Lieutenant General Reinhard Dahl, who not only invited Detlef to the BAF, but also thought of him as the BAF's "poster boy" - handsome, smart and skilled as a pilot. Despite his optimistic views, Reinhard felt sad whenever Fleisher was deployed on a dangerous mission, as he always put himself in danger out of a belief on Belkan patriotism.
Fleisher's flight career truly started in 1994, where he destroyed three Ustian Su-27 Flankers over the strategic Area B7R in May 10. Following this incident, his cunningness and combat strategies earned him the title of Ace. Later on May 15 he eliminated a flight of 5 F-16C Fighting Falcons aircraft on his second sortie, earning him the Belkan Silver Cross Award and widespread fame across Belka, being featured in military propaganda across the country. As time passed, Belkan newspapers started praising the actions of Detlef and the Rot Squadron in the early phases of the Belkan War. However, as his fame grew, people close to him started persuading him to move into safer areas in the military, but he declined, choosing instead to remain as an ace of the BAF.

Feeling grief for his defeat, after being rescued from B7R, Detlef Fleisher decided to leave the Air Force, starting a new career as a base commander. Following the Belkan War he was found guilty as a war criminal, but was exempted from punishment. He remained in Belka, where he became a history teacher at the University of Dinsmark. Ten years later, in 2005, he would be one of the first aces interviewed by Osean reporter Brett Thompson for his documentary, "Warriors and the Belkan War".
Here, he was still clearly bothered by the fact that he was beaten by a mercenary, and tried to rationalize his loss to Cipher.
