Strela 2M, unless I am wrong, is the SA-7, which is more comparable to the old Redeye than the Stinger.
Still bad news for somebody.
Never led media try to ident equipment! The Strela 2 is the SA-7 GRAIL. This is a man-portable SAM. The missile which brought down the F-117 over Serbia was the SA-3 (GOA). It's like trying to compare a US Redeye SAM with a US HAWK SAM!
