51 Special Action Group's mission is part of the NSG's overall mission to neutralize specific terrorist threats in vital installations or any given area, handle hijack situations involving piracy in the air and on the land, engage and neutralize terrorists in specific situations, and to rescue hostages in kidnap situations.
