A Counter-Terrorism Unit (CTU) is a specialized group within law enforcement or military organizations that focuses on preventing, responding to, and investigating terrorist activities. These units are trained to handle various threats, including bombings, hostage situations, and cyber-terrorism. They often collaborate with other agencies, such as the FBI or Interpol, to share intelligence and resources. CTUs employ a range of tactics, including surveillance, intelligence gathering, and community outreach, to identify and disrupt potential terrorist plots. They also work on developing strategies to protect critical infrastructure and public spaces from attacks. Their ultimate goal is to ensure public safety and maintain national security.
