The Ukrainian Naval Infantry was equally affected by the crisis as Russian forces besieged them within their bases. Russia eventually confiscated all military equipment of the naval infantry stationed in Crimea, including the assets of the Ukrainian Naval Aviation, though several planes and helicopters managed to make their way to mainland Ukraine prior to the Russian incorporation of Crimea. The 10th Saki Naval Aviation Brigade, controlling all the Ukrainian Navy's air units, managed to get a number of its aircraft airborne to bases in mainland Ukraine on 5 March 2014. However, more than a dozen aircraft and helicopters undergoing maintenance had to be abandoned.
