The SAS (Special Air Service) is the British Army's counter-terrorist, special force organisation.

The SAS have done many things in history, played a massive part in World War 2, the conflict of Ireland and the invasion of Iraq and Afghanistan and many, many other things, but heres an example of the eliteness:
On 30 April 1980, six Iranian terrorists took over the Iranian Embassy in Princes Gate, London. After six days of unsuccessful negotiations and one hostage's murder, Prime Minister Margaret Thatcher ordered an assault. At 19:26 on Monday 5 May, the SAS went in. More than thirty troopers entered the building, including some who went in across the now famous balcony filmed live by the BBC. A diversionary attack was staged and other troopers went in through the ground floor. One hostage was killed by the terrorists, but within minutes the terrorist threat had been eliminated, with five of the six having been killed and one captured. Of the original 26 hostages, 24 were safe. The operation was hailed as a great success and was to change the way the public viewed the regiment.

The SAS is widely regarded as one of the finest and best-trained special forces units in the world, and is the sole creator of special forces, other special organisations base themselves on the SAS, such as the Americans' Navy Seals and the Germans' KSK.
Damn, the SAS are so elite, I wouldn't want to be on their bad side, they are the most elite, best trained and loyal soldiers of the world. Its like they have auto-aim, they're so great.

Absolute badass motherfuckers. A single 4-man group could probably defend themselves against half of Al-Qaeda. The best exponents of the FN Minimi light machinegun.

The Elitest of the Elite. Equalled but not bettered (in most respects) by The US Navy SEALS, the Russian Spetznaz and Delta Force.
OH MY FUCKING GOD, 1 man from the SAS has a machete and he's gonna gut all of my 99 AK47-armed Talibans. RUN!!!!

Special air service.

The British SAS are the most elite, all powerful suppersoldiers on the plannet. At least ten times better trained than any other nations special forces. Equaled only by the British SBS.
EX 1: Tell an SAS man to fuck off and see what happens.

EX 2: The SAS went on a suicide mission last week, no casualties.

A small group of these guys could wipe out a medium-sized enemy encampment within 2 minutes and disappear into the night.

They are the best because they train to be the best. An SAS training course lasts for 6 months and has only a 1 - 3% pass rate.

Notable SAS operations include:

Operation Nimrod - terrorist siege on the Iranian embassy in London, 1980. Considered the most famous and successful hostage rescue in the world. 5 out of six gunmen were killed and 19 hostages were saved.

The Pebble Island Raid - Raid during the Falklands War in 1982 on an Argentinian air base. 11 Argentinian aircraft were destroyed.

The Loughgall Ambush - massacre of the IRA East Tyrone Brigade in 1987. The SAS attacked eight IRA members who had just bombed an RUC station. All eight bombers were killed.

Operation Barras - the rescue of eleven British soldiers held captive by Sierra Leone's notorious West Side Boys. At least 25 rebels were killed and 18 captured, including the rebel leader. Unfortunately one SAS soldier was killed in action.
The SAS - not people to mess with.

THe australian sas is one of the most gruelling training processes in the world.
