At some point before the Belkan War, Speidel joined the Belkan Air Force and was assigned to the Gault Team.
Following the Belkan War's official conclusion, Speidel and the squadron defected to A World With No Boundaries. On December 31, 1995, they engaged the Galm Team over Area B7R, where Speidel was shot down and killed.
After his death, his house was investigated. Multiple calls to foreign countries were discovered. Due to his close relationship with squadron leader Anton Kupchenko, some believed that he had some part with A World With No Boundaries.
