Seems to be a near total absence of counter battery fire on the part of the resistance. A shortage (or non use) of RPGs. Without such, the “revolution” is over.
The Russians & Iranians are arming Assad. So, unless the resistance gets help, (& it doesn’t look like they will) it’s going to be over soon.
The White House is stalling, hoping it’s over soon so they don’t have to get involved.
They badly need anti-tank weaponry. If they could start taking the tanks out, this thing could turn. Until then, it’s an uphill fight.
