In late summer 1969 the Royal Army G-2 had intelligence which suggested the classical Asian Communist army, with various units in different structural layers. Dated September 1969, the reports mentioned province, village and hamlet formations. Shortly thereafter, other reports appeared that the western rebels had organized battalions. A Khmer Communist officer who defected last year said his battalion formed in early 1970, before Sihanouk's overthrow in march. The defector stated that the cadre who mustered the unit was a Cambodian fresh from training in North Vietnam.
