The Mujahedeen blasted away at the Russians for 20 years wasn’t it? I’m not positive of the exact length, but Russia had them clearly outgunned, out-financed, out-supplied, out-technologied…but they still lost because the Mujahedeen just slowly bled them to death. A sniper attack here…a rocket there…one or two at a time until the Russians got tired of bleeding and left.
