Actually there are only 2 Generals in Latakya (airbase commander Major General and VKS spokesman Leutennant General Viktor Kanashenkov), so no dosen or dosens in Syria. Another 3-4 Generals are in Eurasian Coalition Control and Coordination Center in Baghdad.
Russian Army has the most sophisticated guarding systems in the world.
They can detect any object even in anti-IR cloaks, designate object groups, distinguish humans from animals, armed humans from civillians, detect any explosive on man or on track for several hundred meters from guarding perimeter. And all of this stuff is connected into joint perimeter guard system.
Also there are interesting things to stop the perimeter penetration with or without target destruction including explosive fuzes jamming and/or premature fuze engagement.
