Reports were collected inside the divisions and then transmitted to the Centre level command bodies, these being the General Staff. Commands were issued via the same lines of communication. Central command transmitted its orders to the divisions, where they were further sent to lower level commanders that carried them out. Communication Between Divisions and Centre 137. Communication between the divisions and the Centre was continuous, with several contacts every day.413 The Centre command level regularly communicated with divisions414 and relied on the divisions to forward its commands to lower-level units. Important decisions on the division level were to be taken by the Centre command bodies.415 Divisions sent reports to the Centre command bodies on a regular basis, usually reporting on military engagements, discoveries of internal enemies and other matters.416 138. Communication was facilitated by various means. One of the most common communication lines was via radio and telegraph lines, including oral communication as well as messages.417 To this end, the General Staff418 as well as the individual divisions419 maintained radio and telegraph units. Messages sent and received by RAK were encoded.420 139. Messengers were also frequently used to transport messages.421 Individual divisions had messenger units to provide these services.422 140. Communication between the General Staff or the Military Committee on the one side, and individual divisions on the other side, was frequently forwarded to members of the Central Committee.423 141. Another common means to communicate between the Centre command bodies and the divisions was via in-person meetings.424 Meetings ranged from smaller gatherings425 to large rallies.426 Examples for larger meetings are the meetings conducted before the final attack on Phnom Penh,427 and before the purge of the Eastern Zone.428 Large rallies often included speeches by senior CPK functionaries.429 Some witnesses report that military meetings were held at the Olympic Stadium of Phnom Penh for commanders of units from the battalion level upwards, chaired by Son Sen.430 Extraordinary Chambers in the Courts of Cambodia, National Road 4, Choam Chao, Dangkao Phnom Penh Mailing address: P.O.
