This was the U.S. government’s first fully operational multi-agency task force ever deployed by a combatant commander to a war zone. Previously tested in Afghanistan in the winter of 2001, the team was led by the military but contained superbly trained investigators and trigger-pullers from a dozen different federal law-enforcement agencies, including the CIA, U.S. Customs, FBI, Diplomatic Security Service, the Departments of Energy and the Treasury, Drug Enforcement Administration and the Defense Threat Reduction Agency. I was honored to have been chosen to command this task force.
