L Detachment - SAS
L Detachment (previously known as R Squadron) is a territorial (reserves) unit directly attached to 22 SAS. It is made up of 22 SAS veterans and civlian volunteers. L Detachment's role is to augment 22 SAS, providing additonal manpower and casualty replacements, unlike 21 and 23 SAS who largely act as independant units with their own command structure.
Members of L Detachment (then R Squadron) were first sent into action during Operation Desert Storm in 1991. R Squadron troopers integrated with A and D Squadron Land Rover columns operating behind Iraqi lines.
L Detachment volunteers go through the same selection process as their regular 22 SAS counterparts.
