ISB Enforcement is the Bureau's operational arm. It executes arrest and search authorities, protects investigators and sensitive sites, transports high-risk detainees, and provides tactical capability for internal-security operations.
ISB Tactical Units handle barricaded suspects, fortified locations, hostage situations, and threats requiring specialist entry, breaching, precision fire, or hazardous-environment capability. Military support is requested when the scale becomes a campaign or battlefield problem.
Every operation has a written commander, legal basis, objective, and rules for force. Enforcement personnel use no more force than is reasonably necessary to protect life and complete the lawful mission. Searches and seizures are documented, and evidence is transferred through a recorded chain of custody.
Enforcement is not a general patrol service and does not replace local police or the Judicial Forces. Detainees are transferred promptly to the authority responsible for continued custody. Operational urgency does not confer authority to punish.
