>>63862683There's number of reasons. First is purely organizational - in addition to some regional zoning, Soviets split their academies by the branches of military, thinking if you have specialized rocket academy, the overall quality of the officer staff will be higher.
Second is somewhat related to
>>63863340. Military is still very dynastic in Russia. Same as FSB, same as oil industry, the medicine, even the fucking science. I wouldn't say kids are getting some kind of military upbringing here, despite "Suvorov's Academies" still being a thing, but that still shows. Of course, officers are interested in landing their offspring to some safe and comfortable position, so as a result, officer staff is overbloated with rear bureaucracy working in offices. Also, as already mentioned here, there's no NCOs in Russia.
There's another fun thing you may want to know. There's a "military department" in every notable university ("department" as in "academical department" in college/university). In theory, it should've provide capable
civilian specialists with a means to become reserve officers, getting a military specialization synergistic with their civilian profession, but here's the trick. As the army is conscript-based, anyone should "serve" here for 2 years, either before the college, or after it. But if you get an officer specialization from university's military department - bang, you are already a reservist 2nd lieutenant, no need to stomp kirzachi and suck dick in the barracks for two years.
This system mutated slightly. Back in Soviet times, around mid 1970s, I think, it was so encouraged that everyone and their cat was getting military education that way, even some girls (medics, some scientific professions like chemists, etc). In modern Russia it became possible to buy some medical diagnosis to become unsuitable for conscription, so this was more effortless route to take, but you won't be suitable to become an official of some meaningful kind if you do it
