Drozdov began his officer service in 1983 as a pilot of a fighter aviation regiment in Ivano-Frankivsk.

In 1989-1993 he was a flight leader of a fighter aviation regiment in the Group of Soviet Forces in Germany.

In 2006, he becomes Head of the Aviation Training and Application Department of the Ukrainian Air Force Command.

[3][4] In December 2016, he led the control flight tests of medium-range anti-aircraft guided missiles near Oleksandrivka in the Kherson Oblast.

Prior to that, the former commander of the Ukrainian Air Assault Forces lieutenant general Mykhailo Zabrodskyi, former defense minister Stepan Poltorak, and Servant of the People MP Iryna Vereshchuk requested the court to bail Drozdov out.

[11] On February 23, 2022, on the eve of the new Russian invasion of Ukraine, the Investigative Committee of Russia included Drozdov in the list of 85 Ukrainian military and political figures supposedly involved in “the killings of Russian-speaking people in Donbas”,[12] which followed a pattern of previous cases initiated by Russian authorities against Ukrainian political and military figures, perceived in Ukraine as a form of political psychological pressure.
