Elite units are specialized military groups trained to perform high-stakes missions that require advanced skills and tactics. These units often undergo rigorous selection processes and extensive training to prepare for operations such as counter-terrorism, reconnaissance, and direct action. Examples include the Navy SEALs in the United States and SAS in the United Kingdom. These units typically operate under strict secrecy and are equipped with advanced technology and weaponry. Their missions may involve hostage rescue, sabotage, or intelligence gathering, often in hostile environments. The effectiveness of elite units can significantly impact military operations and national security.
