Counter-Terrorist Units (CTUs) are specialized law enforcement teams trained to prevent and respond to terrorist threats and incidents. They focus on neutralizing terrorist activities, rescuing hostages, and ensuring public safety. CTUs often work closely with other agencies, such as the military and intelligence services, to gather information and coordinate responses. These units employ advanced tactics and equipment, including firearms, surveillance technology, and negotiation skills. Members of CTUs undergo rigorous training to handle high-pressure situations effectively. Examples of such units include the FBI's Hostage Rescue Team in the United States and GIGN in France, both renowned for their expertise in counter-terrorism operations.
