In 2015, Jiaolong commandos participated in the evacuation of 571 Chinese citizens and over 200 other foreign nationals from Yemen after a Saudi-led coalition began airstrikes against the Houthi rebel group (Yemen Civil War).
In April 2017 10 members of the brigade, in coordination with the Indian navy, helped rescue 19 Syrian crewmembers from a hijacked Tuvalu cargo ship in the Indian Ocean.
On 5 May 2017, 3 pirates were captured by the unit and handed over to the Somali Police Force.
The brigade is used for Visit, board, search, and seizure (VBSS), anti-piracy, air assault, direct action, combat diving, sabotage and amphibious reconnaissance.
The brigade has carried out joint exercises with People's Armed Police special operations units.
The 2018 film Operation Red Sea is loosely based on the unit's involvement in the evacuation of Chinese and foreign nationals in the Yemeni Civil War and also depicts the unit.
