Special mission unit
The term Special Missions Unit (SMU), at one time referred to as a "Tier 1" unit,[1] is used in the United States to categorize the nation's most highly secretive and elite military special operations forces.[2] The term "special missions unit" is also used in Australia to describe the Special Air Service Regiment. Special mission units have been involved in high-profile military operations, such as the killing of Osama bin Laden and the attempted hostage rescue of Kayla Mueller.
Australia[edit]
The Australian Army's elite Special Air Service Regiment are described as being "special missions units with unique capabilities within the Australian Defence Force".[20] The Regiments are components of Australia's Special Operations Command (SOCOMD), and are tasked with conducting "sensitive strategic operations, special recovery operations, training assistance, special reconnaissance and precision strike and direct action".[20]
The SASR currently has four sabre squadrons, known as 1, 3 and 4 Squadron.[21] The first two squadrons rotate through the two roles performed by the Regiment; one squadron conducts the counter terrorism/special recovery (CT/SR) role, and the remaining squadrons conduct the warfighting/reconnaissance role, while 4 Squadron is responsible for collecting intelligence and also supports the Australian Secret Intelligence Service.[22]
