That means the Egyptian military will have it hands full. Just saw a report about 400 missiles being taken during the Benghazi debacle.
An article I saw last year had some/most of the SEALs working at Benghazi on recovering Libyan government stocks of SA-22 (successor model to the SA-14's fired at airliners in East Africa several years ago, and to the original SA-7's we've heard about before being used in Iraq) MANPADS, of which several thousand had fallen into the hands of MB-aligned Libyan militants of the same stripe as the Libyan hardcore Al-Q'aedists who were notable fighting in Iraq with Adnan al-Zarqawi.
The SA-22's would be, and now are, a major threat throughout the medium term, to civil aviation worldwide. Imagine if Abu Sayyaf got their hands on several dozen in the Philippines. Lovely.
