Russia's armed forces chief, General Valery Gerasimov, says the Russian flag is now flying over all 193 military facilities in Crimea, RIA Novosti reported.
His statement came one day after pro-Russian forces seized the last Crimean warship still under Ukrainian control.
According to Crimea authorities, more than 15,000 Ukrainian servicemen have applied to switch over to Russian law-enforcement agencies following the peninsula's annexation by Russia.
Another 1,500 Ukrainian servicemen are reportedly preparing to return to mainland Ukraine with their families.
Gerasimov said they would soon be able to leave freely by rail.
