Sources who have debriefed the team that was at the CIA annex the night of the attack in Benghazi say that the CIA operators from the Global Response Staff, or GRS, were equipped with Mark 48 machine guns and had two types of laser capability. Each weapon had both a “passive” as well as a “visible” laser that could be used against the Libyan attackers.

The presence of laser capability on the roof of the CIA annex confirms what Fox News sources that night in Benghazi originally said, which is that they had laser capability and for 5 hours and 15 minutes were wondering where the usual overhead air support was, especially since, according to this source, they radioed from the annex beginning as early as midnight asking for it.

The presence of lasers raises more questions about why air support was not sent to Benghazi even protectively once it became clear that the fighting had followed the CIA rescue team back to the annex.

US military officials say they "thought the fighting was over" after the team left the consulate and that there was a lull in the fighting.

Fox News has learned the guns were fitted with PEQ-15 lasers. The “passive” laser is not visible to the naked eye but can help team members identify hostile forces when the shooter is wearing NODS, or Night Observation Device attached to their helmet. The visible laser system places a red dot on the attacker and warns the attacker not to shoot, encouraging them to flee the scene. US troops often use the visible laser to scare children or other civilians who find themselves in the middle of combat activity. When civilians see the laser they often back off in order not to be shot.

The GRS team that was present at the CIA annex provided security for the CIA station, as they do around the world. They are highly trained in countersurveillance, close target reconnaissance and in depth reconnaissance. Enemy fighters have learned in Afghanistan and Iraq to use their cell phones to follow or intercept these “passive” lasers without having night vision or NODS.

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.
