Say the name "SAS" to someone and it conjures up images of elite commandos from the United Kingdom. The British are not the only ones with a group of highly trained operators however; the US Central Intelligence Agency controls an American group of SAS, known as the Special Activities Staff. The US SAS is a little known unit in the secretive Directorate of Operations section within the CIA. While not a military unit, the SAS is considered an actice Special Missions Unit and is tasked with many different activities, ranging from long-range surveillance and bomb-damage assesments to prisoner-snatches and material recovery and sabotage.
The SAS is split into three branches, ground, maritime, and airborne. The Ground branch handles all land assaults and land-based combat activities. The maritime branch handles all water ops and assaults. The air branch is a modern "Air America" but serves the US all over the world instead of just in Asia and also operates many different type of aircraft in civilian markings. If the ground branch needs to insert in to a special local it is the air branch that gets them there.
Very little about this group is known, but it is known that they recruit many of the best operators in the US. Former members of the Navy SEALs are believe to provide a regular portion of the SAS's members.
