The treaty was ratified by the Federal Assembly and Federation Council by 21 March. A Just Russia's Ilya Ponomarev was the only State Duma member to vote against the treaty. The Republic of Crimea and the federal city of Sevastopol became the 84th and 85th federal subjects of Russia. During a controversial incident in Simferopol on 18 March, some Ukrainian sources said that armed gunmen that were reported to be Russian special forces allegedly stormed the base. This was contested by Russian authorities, who subsequently announced the arrest of an alleged Ukrainian sniper in connection with the killings, but later denied the arrest had occurred. The two casualties had a joint funeral attended by both the Crimean and Ukrainian authorities, and both the Ukrainian soldier and Russian paramilitary "self-defence volunteer" were mourned together. As of March 2014 the incident was under investigation by both the Crimean authorities and the Ukrainian military. In response to shooting, Ukraine's then acting defense minister Ihor Tenyukh authorised Ukrainian troops stationed in Crimea to use deadly force in life-threatening situations. This increased the risk of bloodshed during any takeover of Ukrainian military installations, yet the ensuing Russian operations to seize the remaining Ukrainian military bases and ships in Crimea did not bring new fatalities, although weapons were used and several people were injured. The Russian units involved in such operations were ordered to avoid usage of deadly force when possible. Morale among the Ukrainian troops, which for three weeks were blockaded inside their compounds without any assistance from the Ukrainian government, was very low, and the vast majority of them did not offer any real resistance. On 24 March, the Ukrainian government ordered the full withdrawal of all of its armed forces from Crimea. Approximately 50% of the Ukrainian soldiers in Crimea had defected to the Russian military. On 26 March the last Ukrainian military bases and Ukrainian Navy ships were captured by Russian troops.
