As the Syrian military begins its push to take back opposition-held areas in northwestern Syria, Russia has provided backing through an intensifying aerial campaign.
Among the planes Moscow has used to back the Syrian military's attempted advance is a Russian combat aircraft that some have compared to the US's venerated A-10 Warthog.
During the Soviet invasion of Afghanistan, the CIA provided Stinger missiles to anti-Soviet forces, weapons that allowed the mujahedeen to down enemy transport planes and attack helicopters. The use of the missiles bogged down Soviet forces and led to an eventual Soviet withdrawal from the country.
The US has consistently opposed the idea of providing MANPADs and other anti-aircraft weaponry to Syrian rebels, as the weapons could conceivably end up in the hands of al Qaeda or its affiliates and could be used to down a civilian airliner or a US military aircraft.
At least for now, the Frogfoots are largely uncontested in Syria's skies.
