Specifically, I have not encountered the military-industrial complex. In principle, I came across the state security sphere. I can confirm that there is a tendency there to make money on government spending.
In some cases, it is surprising how one can approach the field of state security in this way, since instead of state security, it turns out to be state security.
It's like in an anecdote: The camel was asked: "Why is your back a curve?" He didn’t think long and asked in response: “What is direct?”
I have no exact information about how and who steals in the military-industrial complex, but knowing the landscape, I can confidently assume that if sawing in all other areas (not only in the oil industry), then sawing there too. Moreover, in the military-industrial complex, it is much easier and safer to do this, since the state. purchases are not published and items of expenditure are mostly classified, even from State Duma deputies.
By the way, I completely forgot something, I'm adding. Not directly the military-industrial complex, but very, very close. Everyone remembers the story of OboronService and the machinations established by the court (albeit with a completely ridiculous verdict to the defendants in the end) or has it already been forgotten?
