Intelligence Specialist (IS) is a US Navy enlisted rating within the Information Warfare community. The Intelligence Specialist rating was established in 1975 by combining the Photographic Intelligenceman (PT) rating (first established in 1957) and parts of the Yeoman (YN) rating. Initial training ("A" School) was conducted at Lowry Air Force Base in Aurora, Colorado until 1994 when the school was moved to the Navy Marine Corps Intelligence Training Center (NMITC) in Dam Neck, VA. As of September 2018, there are roughly 2950 enlisted Intelligence Specialists in the US Navy.
