The active reserve was significantly expanded in Post-Soviet Russia, when a majority of positions in the Russian power elite were occupied by acting or undercover officers of the Russian state security services, such as the FSB and SVR, the official successors of the KGB. "The only difference between them [officers of active reserve] and regular civil-servants is that they have an extra duty: writing reports every month for the FSB. They are the eyes of the master”, said sociologist Olga Krychtanovskaia.
