SAA doesn't make a move without RU support... inb Every SAA advance, RU is in it...
Every push, meeting, control etc... is made by RU...
Right now Attacking SAA is like Attacking RU...
But as long as ASSad is not officially put on the enemy list... then you can't do much.
Except for Countries like the US... But even them do not target groups that are fused with RU official HQ.
Like in Deir ez Zor last year... Where the US chose meticulously the targets that weren't "RU army" linked. that end up killing dozen and dozens of SAA and RU mercenaries from the Wagner group....
Since that move, RU almost always show their direct support on the ground when SAA make any advance... in a way to divert such event to happen again.
