See, I think this is where my initial post is being misrepresented. I understand things in Cinema are embellished, dialogue, action, etc.
What I meant in my opening post was that this movie puts the surrounding sub points into perspective. The strategic decisions leading up to the night WRT security for the ambassador, the facility, the decision to delay the GRS guys from going to the compound (the only thing that could theoretically have saved the ambassador), the reality of indigenous support, and how fast things turned badly. It also puts into perspective that we left the CIA station basically out to dry. The time has always been the thing that I have been most concerned about around this event. It lasted 13 hrs. hypothetically, that's almost enough time to get a Delta team from Bragg to Benghazi. The notion that we did nothing was extremely disconcerting to me.
If there was indeed a UAS asset overhead, the video on that feed was piped into every TOC from the local CIA outpost to AFRICOM HQ to the White House. You could see what was happening and you could easily see they were under a heavy assault.
