as the Kedah-class offshore patrol vessels are carried out around the island. The Royal Malaysian Air Force also operate frequently on the airstrip. Several anti-ship and anti-aircraft guns are placed on several areas on the island and the RMAF personnel operate a Starburst air defence system to prevent low-level air attacks. The rest of the stations were originally floating barge type habitat modules constructed on mainland Malaysia. Location selection and module positioning was done during high tide so that they could be more easily anchored during low tide and after found satisfactory, the modules were landed and filled in with cement and rocks to strengthen their anchorages. They are all also equipped with radar and ship docking facilities as well as water and power generation facilities. Soldiers are stationed on all stations.

In peacetime, the unit is tasked with responding to maritime hijacking incidents as well as protecting Malaysia's numerous offshore oil and gas platforms. Its wartime roles include seaborne infiltration, sabotaging of enemy naval assets and installations, and the defence of RMN vessels and bases. This unit is analogous to the United States Navy SEALs. On 15 April 2009, PASKAL was renamed KD Panglima Hitam (KD being the equivalent of HMS in the Royal Navy). The ceremony was held at the RMN Lumut Naval Base to honour PASKAL's courage and loyalty to the nation. Panglima Hitam was the name given to brave and loyal Malay warriors who served during the golden age of the Malay Rulers (Sultans and Rajas) of Perak, Selangor, Johor and Negeri Sembilan.
