Yeah it was both AAA and small arms fire I think - pretty much everything they had, they shot.IIRC that was AA artillery. As I understand it, Kerbala was a employment/doctrinal failure. Using attack helos for deep battle proved not to be a good idea.
Using Cobras for CAS and Kiowas for recce seemed to be OK.
Dunno about Afghanistan, though.
Afghanistan was heavy and medium MGs during Tora Bora, in more of the CAS role. The Apaches had to be withdrawn and they resorted to carpet bombing.
Regardless, it's safe to say that unarmoured Tigers would not have come off a lot worse from AAA and small arms hits.
