The Mobile Brigade Corps () abbreviated Brimob is the special operations, paramilitary, and tactical unit of the Indonesian National Police (Polri). It is one of the oldest existing units within Polri. Some of its main duties are counter-terrorism, riot control, high-risk law enforcement where the use of firearms are present, search and rescue, hostage rescue, and bomb disposal operations. The Mobile Brigade Corps is a large component of the Indonesian National Police trained for counter-separatist and counter-insurgency duties, often in conjunction with military operations. The Mobile Brigade Corps consists of 2 (two) branches, namely Gegana and Pelopor. Gegana is tasked with carrying out more specific special police operations tasks such as: Bomb Disposal, CBR Handling (Chemistry, Biology, and Radioactivity), Anti-Terror (Counter Terrorism), and Intelligence. Meanwhile, the Pelopor are tasked with carrying out broader and paramilitary special police operations tasks, such as: Riot control, Search and Rescue (SAR), security of vital installations, and guerrilla operations. The Mobile Brigade Corps are capable of other operations that support the performance of general police units. The Brimob Corps is classified as a Police Tactical Unit (PTU) and is operationally a Police Special Weapons and Tactics (SWAT) unit (including Densus 88 and Gegana Brimob). Each regional police (Polda) in Indonesia has its own Mobile Brigade unit.
