The Washington Post reports: The rapid collapse of a U.S. diplomatic compound in Libya exposed the vulnerabilities of State Department facilities overseas. But the CIA’s ability to fend off a second attack that same night provided a glimpse of a key element in the agency’s defensive arsenal: a secret security force created after the Sept. 11, 2001, attacks.

Two of the Americans killed in Benghazi were members of the CIA’s Global Response Staff, an innocuously named organization that has recruited hundreds of former U.S. Special Forces operatives to serve as armed guards for the agency’s spies.

The GRS, as it is known, is designed to stay in the shadows, training teams to work undercover and provide an unobtrusive layer of security for CIA officers in high-risk outposts.

But a series of deadly scrapes over the past four years has illuminated the GRS’s expanding role, as well as its emerging status as one of the CIA’s most dangerous assignments.

Of the 14 CIA employees killed since 2009, five worked for the GRS, all as contractors. They include two killed at Benghazi, as well as three others who were within the blast radius on Dec. 31, 2009, when a Jordanian double agent detonated a suicide bomb at a CIA compound in Khost, Afghanistan.

GRS contractors have also been involved in shootouts in which only foreign nationals were killed, including one that triggered a diplomatic crisis. While working for the CIA, Raymond Davis was jailed for weeks in Pakistan last year after killing two men in what he said was an armed robbery attempt in Lahore.

The increasingly conspicuous role of the GRS is part of a broader expansion of the CIA’s paramilitary capabilities over the past 10 years. Beyond hiring former U.S. military commandos, the agency has collaborated with U.S. Special Operations teams on missions including the raid that killed Osama bin Laden and has killed thousands of Islamist militants and civilians with its fleet of armed drones.
