The A-10 might be MANPAD resistant to the SA-7 (Grail class and variants), but it wasn't designed to survive anything newer. Yes it has redundant control mechanisms/engines, titanium bathtub and tails. But it's still easy to target with IR, not to mention radar.
And against a modern AD system, it'll be toast. Whether it's a Tunguska or worse, it can't survive on the modern battlefield until these systems are attritted via SEAD.
