After reading this report I'm wondering how would Hezbollah perform if they could use SAM's as close protection agains Israeli air force. What is your oppinion?

I didn't find any mention of mortarts used by Hezbollah. Couldn't be mortars effective counter measure against infantry that covered Israeli tanks. Report says that Israelis couldn't intercept short range Katyushas. Can we make parallel and say that Israelis are not able to spot possible Hezbollah's mortar batterys. Does anyone know if mortars in that kind of conflict are vulnerable to Israeli counter-battery radars? Is this kind mortar tactics already passed phase on Hezbollah's learning curve?
