still think they should be wearing body armour, helmet, and armoured vehicle such as Tigr-M etc etc. still cant be sure everything is safe and everyone is who they are, it only takes a spy or suicide bomber to end the life of one of these important people.
The Colonel General is following the RA's standard operating procedure in Syria of treating the population in the same way as the SAA Generals and soldiers, that is as friends who are not about to attack them. You can see how well it works. Compare and contrast with the US military leaders, who will only venture out like that when surrounded several deep by bodyguards, whilst the Russians have them they are few and well back. This is seriously deep penetration of Syrian society. Something the US in the ME can now only dream of.
On the other hand, given his shape I'd say that the Major General was wearing armour and he needs it, he is not with friends. It is a pity there seems to be no wide angle or helpful shot as to what the surrounds look like but we can put money on him certainly and the CG probably, traveling in something armoured.
Still puzzled by a Russian 2* being where he was, meeting a US 2* perhaps? There has certainly been a lot of US helicopter movements in the area lately.
