That area is densely populated, and government buildings are everywhere as the city is separated into many smaller administrative areas and that’s before you get into the oblast and the surrounding conglomeration of cities/towns that pretty much merge into Moscow (Reutov, Balashikha, Podolsk, Dolgoprudny, Dzerzhinsk, Lyubertsy, Mytishchi, Khimki, Odintsovo, Nakhabino etc etc), many of which are huge military areas too, I’m not doubting anything as I genuinely don’t know, but closing of government buildings quietly would be a massive undertaking involving significant manpower… of course they may be more selective in which government buildings to focus on, but I just hope they have the right paperwork because the inevitable babushka receptionists will not accept anything less than everything signed in triplicate or you ain’t closing anything, ak-47 or not!
