in small teams, typically made up of two to ten operatives (with some operations being carried out by a single officer), all usually with extensive military tactical experience and a set of specialized skills that does not exist in any other unit. As fully trained intelligence case officers, paramilitary operations officers possess all the clandestine skills to collect human intelligence – and most importantly – to recruit assets from among the indigenous troops receiving their training. These officers often operate in remote locations behind enemy lines to carry out direct action (including raids and sabotage), counter-intelligence, guerrilla/unconventional warfare, counter-terrorism, and hostage rescue missions, in addition to being able to conduct espionage via HUMINT assets. There are four principal elements within SAC's Special Operations Group, formerly called branches, now organized as departments: the Air Department, the Maritime Department, the Ground Department, and the Armor and Special Programs Department. The Armor and Special Programs Department is charged with the development, testing, and covert procurement of new personnel and vehicular armor, and maintenance of stockpiles of ordnance and weapons systems used by the SOG, almost all of which must be obtained from clandestine sources abroad, in order to provide SOG operatives and their foreign trainees with plausible deniability in accordance with U.S. Congressional directives. Together, the SAC/SOG comprises a complete combined arms covert paramilitary force. Paramilitary operations officers are the core of each branch and routinely move between the branches to gain expertise in all aspects of SOG. As such, paramilitary operations officers are trained to operate in a multitude of environments. Because these officers are taken from the most highly trained units in the U.S. military and then provided with extensive additional training to become CIA clandestine intelligence officers, many U.S. security experts assess them as the most elite of the U.S. special missions units. Paramilitary operations officers require a bachelor's degree to be considered for employment. Many have advanced degrees such as master's degrees or law degrees. SAC officers are trained at Camp Peary, Virginia (also known as "The Farm"), "The Point" (Harvey Point), a facility outside of Hertford, North Carolina, and at privately owned training centers around the United States. In addition to the eighteen months of training in the Clandestine Service Trainee (CST) program required to become a clandestine intelligence officer, paramilitary operations officers are trained to a high level of proficiency in: the use and tactical employment of
