The military branch of the KPNLF was the Khmer People's National Liberation Armed Forces (KPNLAF). Established originally in March 1979 by General Dien Del, it was commanded by Sak Sutsakhan from 1981-1992 (with the exception of some power struggles). However, in an individual unit the commander was relatively autonomous, therefore General Sak had the difficult job of coordinating the actions of each unit. This understandably led to a lot of confusion and relative ineffectiveness for large-scale battles. On the other hand, this organization reaped benefits in the form of greater flexibility and mobility of the armed forces.
