The SAA would fall easily if it wasn't for the RUAF, let's be real here. Looking at the combat vids of the rebel forces and studying their gear, tactics and determination, the SAA would have no chance. The only thing keeping the SAA in Saraqib is powerful RU airstrikes that obliterate 10 houses with one bomb, therefore, there is no way the rebels can hold any town or city as long as the RU airforce reigns free.
The only way the rebels can achieve success with holding ground is by launching a massive frontal attack consisting of 5-10 thousand troops attacking positions from from Rabia to Zahraa supported with TR artillery and drone strikes. All the while use Koral to jam RU planes, and use smoke grenades in the offensive attack to hide movements from the airforce (as much as possible), and throw in a few dozen manpads into the mix and suddenly you create a uncontrollable situation for Russia.
Such a massive offensive would bring the Russians to the table real quick.
These small scale attacks on one town at a time is not going to accomplish anything.
This is Wagner not regular Ru forces.
