The Yamam is capable of both hostage-rescue operations and offensive take-over raids against terrorist targets in civilian areas. Besides military and counter-terrorism duties, it also performs tactical unit duties and undercover police work.

Counterterrorism, also known as anti-terrorism, relates to the practices, military tactics, techniques, and strategies that governments, law enforcement, businesses, and intelligence agencies use to combat or eliminate terrorism.
