Over at the jetcareeers.com forum there are a bunch ex military pilots. This one in particular used to fly the F-117 and A-10.
Here's what he had to say about the the SA-10.

That whole thread is interesting to read the current and ex-mil pilots' perspective on the F-35 and why it's needed. The TLDR is the that A-10 would never survive going up against an opponent who could field modern air defenses.
