The granddaddy and model for all modern special forces was created in 1950 and is mainly tasked with counter-terrorism in peacetime and special operations in wartime. They came to the public eye after a daring and successful raid on the Iranian Embassy in London to rescue hostages during the 1980 Iranian Embassy siege. The British SAS follow the same sea, air and land training as the US SEALs, but receive more in-depth and complex counter-espionage training than their American counterparts, making them truly invaluable on the field. That said, the SAS and SEALs often work and train together. They are trained in numerous fighting techniques and remain the primary model in which most national commando units are based.
