Ахмад Шах Масуд
Daud studied engineering in college. After graduating from college in the 1991, he defected from the Afghan Army and joined the forces of Ahmad Shah Massoud against the Soviet invasion of Afghanistan. After the retreat of Soviet troops and the defeat of the Afghan communist regime, Daud remained in Takhar province of Afghanistan. Ahmad Shah Massoud had ordered him to guard northern areas and to keep his forces out of the capital Kabul. When the Taliban took power in Kabul, Daud served as a leading military commander of the anti-Taliban United Front under the command of Ahmad Shah Massoud, which later spearheaded the defeat of the Taliban. In October 2001, Daud was directly responsible for retaking the city of Kunduz from an Al Qaeda-Taliban alliance.
