History
The SDU was established in 1974 by the British Hong Kong Government in response to the ever-increasing threat of international terrorism.
The SDU, then consisting of ten odd members, used existing police weaponry and devised their own tactics.

Organisation
The Special Duties Unit consists of a support group, administration group, and the action group. The action group is the core of the SDU, further categorized into the assault team and the sniper team.
The SDU structure consists of the following as of 2014:
* Administration Group (Headquarters) which is responsible for all administrative works, as well as providing intelligence to operations
* Action Group
** Assault Teams
*** Team A, Team B, Team C (Training of SDU officers)
*** Sniper Team
** Boat Team: Provides sea transportation for the assault team, and maintains the SDU fleet of small vessels
* Support Group
** Medical Support Team: Consists of combat medics who perform operations along the assault team
** Transportation Team: Maintains the SDU fleet of land vehicles

Selection and training
A volunteer for the SDU has to successfully complete an 11-day selection course known as Hell Week which is held annually that has a success rate of only 25%.
After successfully completing selection, the applicant is required to complete a nine-month training course that includes weapons handling and marksmanship, tactical movement, unarmed combat, breaching, climbing and roping, chemical, biological, radiological and nuclear incidents, and combat medicine.
Applications are open to women officers, with no female officers to date.
Between 1974 and 2014, 383 officers had served in the SDU.
Prior to 1998, the SDU selection course was 10 to 14 days in length with most of the emphasis placed on physical endurance.
In 1998, this changed to a basic four-day selection course with more emphasis on mental attributes than physical ones.
Those who successfully passed the basic selection course were given a five-week build-up course followed by a week-long advanced selection course.
The course concentrated on weapons handling and use, elementary close-quarter battle, camouflage and concealment, physical fitness, observation and commentary, first aid, and map reading.
For the period 1998–99, 44 officers applied with 14 selected.
Equipment and weapons

SDU officers deploy in Crye Precision G3 combat dress of various camouflage patterns depending on the environment. Officers may also deploy in plain clothes during a rapid response when there is no time to change. Armor and accessories include Ops-Core FAST ballistic helmets

In 2020, the United States, the United Kingdom, and the European Union, placed restrictions on the sale of military equipment to Hong Kong following the passing of the
national security law. As a consequence, an order of 1000 replacement MPX submachine guns and SIG516 assault rifles for the SDU and other units placed in early 2021 was cancelled by SIG Sauer, and the Hong Kong police will need to source firearms elsewhere for all units, including the SDU.
