Hogan's Alley is a tactical training facility of more than 10 acres (40,000 m²) operated by the FBI Training Academy. Hogan's Alley was opened in 1987, and was designed to provide a realistic urban setting for training agents of the FBI, DEA, and other local, state, federal and international law enforcement agents. The term "Hogan's Alley" is also used generically to refer to any shooting range devoted to tactical training.
Hogan's Alley consists of a street with a bank, a post office, a hotel ("The Dogwood Inn"), a laundromat, a barber shop, a pool hall, homes, shops, and more, many of which are named after events in the FBI's past. The town is populated by actors who role play parts appropriate to the training that is in progress; most play innocent bystanders, but some play terrorists, bank robbers, drug dealers, or other criminal roles. One of the buildings really houses a classroom for training agents on site, another houses a working FBI office used in some simulated scenarios.
Hogan's Alley is used to teach agents investigative techniques, firearms skills, and defensive tactics. Scenarios involve investigations of terrorist activities, planning and making arrests, processing evidence at crime scenes, conducting interviews and searches, using ballistic shields as protection, and clearing areas and buildings so they're safe to enter. Simulated munitions, which are essentially realistic paintball guns, are used in simulated gun fights with the criminal role players.
