I too wonder where the air support was. Why didn't the Obama admin protect our people? Was Obama afraid to anger Muslims? Libyans? Was he afraid of drawing attention to his failed foreign policy? Is that why they tried to blame Al Qaeda's attack on a mob and a video?
The Annex team also had Ground Laser Designators, or GLD. This kind of laser equipment emits code and signal when there is overhead air support, unmanned aerial surveillance, drones or Spectre gunships, for instance.
A source present the night of the attack says that the GRS team that was defending the annex asked where the air support was at midnight. Former SEALs Tyrone Woods and Glen Doherty were killed 5 hours and 15 minutes later.
