How many planes did the Soviet Union lose to Stinger missiles during Afghanistan War? I have read Wikipedia articles about the war in Afghanistan, and it is often said that the Stinger had a great impact on the air mobility of the Soviet military.

Beside the role of interdiction (A2AD) of the helicopters to go to the mountains and deliver assault and special troops, did the American-built missile destroy or damage a lot of airplanes and helicopters?

What sort of technologies and tactics did the Soviet Union deploy to avoid being shot down?
This quotes an estimate of 269 aircraft, but I think its hard to find the exact number:
