Former Soviet Union countries inherited most of their military hardware from the Soviet military units were stationed there before the Soviet Union collapsed. How did they decide who was going to get what after the Soviet Union collapsed?
Given that the Soviet armed forces were ultimately commanded from Moscow, upon the collapse of the Soviet Union, why didn't Russia just order all of their tank and plane crews to move everything back to Russia?
In general, when the Soviet Union collapsed, had they already worked out what the new lines of command would be, or were things unclear for a while? If you were a Soviet soldier who was a citizen of the RFSR but stationed outside of Russia, say, Uzbekistan, did you automatically become part of the Uzbek military, or get recalled back to Russia?
Not to discourage further answers, but I touched on this topic in previous answers I wrote here and here.
The long and short is that there were some attempts to maintain a Union-wide military as a "Commonwealth of Independent States" military even after the Soviet collapse, and this wasn't totally abandoned until 1993. Regardless, Russia inherited the main bulk of Soviet forces in the former USSR, often even those stationed in such other Republics such as the Baltics and Tajikistan. A few republics, such as Belarus, Kazakhstan and Uzbekistan ended up gaining control over Soviet units based in their respective republic's territory, but the main winner (and main reason no integrated CIS military formed) outside of Russia was Ukraine, which replaced all senior officers in Ukrainian territory with ones willing to swear loyalty to an independent Ukraine.
