SA2s are certainly around in Somalia, there used to be an entire battery of them abandoned next to Berbera airfield in the north of the country, complete with radar, command vehicles etc. I'd have thought that the SA2 was a fairly technical system (liquid fuel?) and would be a real handful for the Somalis to resurrect and operate. There were persistant rumours in 93 that Aideed had got hold of SA7s too, but thankfully they never appeared. Interesting to read in the above link that the Indian Army had missile helos in Somalia. Anyone know where they were based, coz I never saw one? Mind, the Eyeties had a bunch of helos, (CH47s and Mangustas) there too, and they never flew either.
Remember the SA2 took out Gary Powers in his U2 at 60,000' in 1960 something, big reach but probably not very accurate.
And who in thier right mind sees a missile coming at them and does not warn ATC and other traffic? Sounds real odd, that.
