     A-10 just isn't whiz-bang enough for CAS roles because 
     it can't run 13 nested levels of hypervisors and K8s.

The A-10 isn't whiz-bang enough for CAS roles because anti-air defenses are good, nearly ubiquitous, and cheap. And increasingly, man-portable.

If you're fighting a foe more advanced than "some guys with AK-47s" then your A-10 will not be particularly survivable in 2014.

Imagine a foe advanced and wealthy enough to have armored vehicles but it can't afford MANPADs or SAM installations.
