The Office of Intelligence is a subcomponent of HSI that employs a variety of special agents and Intelligence Research Specialists to facilitate HSI's tactical and strategic intelligence demands. Collectively, these intelligence professionals collect, analyze, and disseminate intelligence for use by the operational elements of DHS. The Office of Intelligence works closely with the intelligence components of other federal, state, and local agencies. Many HSI field offices assign intelligence analysts to specific groups, such as financial crimes, counter-proliferation, narcotics, or document fraud; or they can be assigned to a residential intelligence unit, known as a Field Intelligence Group (FIG). HSI agents assigned to FIGs generally focus on Human Intelligence (HUMINT) collection. International Operations, formerly known as the Office of International Affairs (OIA), is a subcomponent of HSI with agents stationed in 60 locations around the world. HSI's foreign offices, known as Attaché Offices, work with foreign governments to identify and combat transnational criminal organizations before they threaten the United States. IO also facilitates domestic HSI investigations by providing intelligence from host countries, conducting collateral investigations, and facilitating international investigations conducted by field offices within the United States. Seventeen HSI field offices maintain a Special Response Team (SRT) that operates as a federal SWAT element for the office's area of responsibility (AOR). SRT was founded under the U.S. Customs Service as the Warrant Entry and Tactical Team (WETT) and were renamed to SRT in 1998. The SRT handles HSI's high-risk arrest and search warrants, barricaded subjects, rural area operations, VIP protection, sniper coverage for high-risk operations, and security for National Security Events. HSI's active SRTs are located in Tampa, Miami, Arizona (Phoenix), New Orleans, Houston, New York, Boston, Dallas, Los Angeles, San Antonio, San Juan, Detroit, San Francisco, El Paso, Chicago, San Diego and Washington, D.C. There is also a team of instructors and coordinators stationed full-time in Columbus, Georgia. These teams primarily deploy to handle high-risk operations, but also assist in events such as Hurricane Katrina, the Haiti earthquake 2010, and other natural disasters around the globe. SRT is a collateral duty open to HSI special agents assigned to an office with a certified team. To qualify, candidates must pass a physical fitness test, qualify with multiple firearms by shooting 90% or better in full tactical gear, and pass an oral interview process.
