[3] Funded, equipped, and trained by the United States and Japan, the UNGERIN operates out of the RMP's Marine Police Main Base in Port Klang, Selangor.

[4] Established in March 2006, the Unit Gempur Marin was created under the Royal Malaysia Police with the first name as the Unit Selam Tempur due to the pressing need of suppressing pirate attacks alongside the coastal area of Malacca Straits and open sea area of South China Sea which were continuously widespread from time to time despite various efforts done to overcome the problem.

[4] The roles of the RMP UNGERIN are predominantly focused on, but not restricted to the littoral and riverine waterborne domains, including: For this, UNGERIN operators are to patrol the following places:[4] Based on this critical need, a specific doctrine from RMP led to the establishment of a marine elite unit performing said task.

Approximately 30 members of the squad (69 Commando personnel were sent to this unit), and the unit will be upgraded to a strength of 100 in the future with 70 personnel employed in stages in the duration of two years after receiving approval from the Public Service Department, which are divided to three detachments, to guard the waters of Malacca Straits and the Sulu Sea.

UNGERIN officers are frequently seen armed with an M4A1 carbine when a maritime operation or a raid is being conducted while the Walther P99QA pistol is used as the standard-issue sidearm.

These have 22 passengers capacity and 30 knots speed, and are possibly equipped with 12.7mm NSV machine gun, 40 mm grenade launcher and 120m Patria NEMO mortar for use by marine police as well as UNGERIN operatives for amphibious assault duties even in shallow waters.

All operatives are equipped with lightweight PRO-TEC helmets, fire-resistant Nomex coveralls, or BDUs (battle dress uniform), plate carriers for carrying ammunition and specialist equipment, tactical gloves, balaclava or protective face covering, protective eye goggles, gas masks, flashlight (usually a Surefire or Heckler & Koch brand), combat steel reinforced boots, flexi-cuffs, and thigh ammo.

Other than the official duties of storming, searching and "cleaning up" the villages the terrorists entered, the UNGERIN has also been busy doing something similar, but in charge of coastal areas.
