Son Sen
During the Democratic Kampuchea days, the 68,000-member Khmer Rouge-dominated CPNLAF (Cambodian People's National Liberation Armed Forces) force, which completed its conquest of Phnom Penh, Cambodia in April 1975, was renamed the LAK (Liberation Army of Kampuchea). This name dated back to the peasant uprising that broke out in the Samlot district of Battambang Province in 1967. Under its long-time commander and then Minister of Defense Son Sen, the LAK had 230 battalions in 35 to 40 regiments and in 12 to 14 brigades. The command structure in units was based on three-person committees in which the political commissar ranked higher than the military commander and his deputy.
