The YAMAM is an Israeli elite counter-terrorism unit, one of four special units of the Israel Border Police. The Unit is capable of both hostage-rescue operations and offensive takeover raids against targets in civilian areas. 

Their primary role is related to SWAT duties and undercover police work, but they are often engaged in military operations.

Yamam is designated as Israel's Anti-Terror unit and unlike regualr SWAT teams - they are far superior and used mostly in special terror events.
