The RMR, short for Royal Marine Regiment, functioned as a highly skilled military division within the Royal Naboo Security Forces.
In the era of the Galactic Civil War, the Royal Marine Regiment executed a raid on the Mauler stronghold located close to Keren. This operation resulted in the deaths of key Mauler figures: their chief strategist, Zolo Sartain, their security head, Yarick Tempol, the hired killer Xylan Kee'choap, and the mystic Walus Mutin.
