This was buried in a post I did earlier but I really feel like it needs to be pointed out. An armed drone was also circling overhead and did nothing.

[I]n fact, at least one member of the team was on the roof of the annex manning a heavy machine gun when mortars were fired at the CIA compound. The security officer had a laser on the target that was firing and repeatedly requested back-up support from a Specter gunship, which is commonly used by U.S. Special Operations forces to provide support to Special Operations teams on the ground involved in intense firefights. The fighting at the CIA annex went on for more than four hours — enough time for any planes based in Sigonella Air base, just 480 miles away, to arrive. Fox News has also learned that two separate Tier One Special operations forces were told to wait, among them Delta Force operators.
