In the early 1990s, the military camps of the RSO were located in the Cox's Bazar District in southern Bangladesh. RSO possessed a significant arsenal of light machine-guns, AK-47 assault rifles, RPG-2 rocket launchers, claymore mines and explosives, according to a field report conducted by correspondent Bertil Lintner in 1991.[1] The Arakan Rohingya Islamic Front (ARIF) was mostly armed with British manufactured 9mm Sterling L2A3 sub-machine guns, M-16 assault rifles and .303 rifles.[53]
