British SAS (22nd SPECIAL AIR SERVICE REGIMENT)

Background
The British Ministry of Defense's official attitude toward commenting on the 22nd SAS Regiment is not to discuss the SAS at all. From details that have emerged through other channels, a sketchy picture of the regiment comes forward, partly due to the fact that many aspects of the U.S. Army's Green Berets are partly based on the missions and structure of SAS.

SAS soldiers, based in Hereford, England, undergo unusually stringent training prior to acceptance into the regiment. In addition to mastering small unit tactics, all aspects of combat and individual specialties, SAS members must endure great hardship and pass rigorous psychological tests during selection and training. In recent campaigns, the SAS profile has been raised due to remarkable details surrounding their missions that have made their way to the public. Nonetheless, members of the regiment surround themselves and their identities in secrecy.
