01005802 Case File No. 002/19-09-2007/ECCC/TC E313 Centre Divisions were sub-divided into smaller units. Typically, there were three regiments to a Division; three battalions to a regiment; three companies to a battalion; three platoons to a company; three squads to a platoon; and around 12 soldiers to a squad.765 At the level of the company and above, each echelon was headed by a commanding officer (also known as a ‘chairman’ or ‘commissar’), usually assisted by two subordinates.766 244. A number of witnesses indicated that there was an additional command level between the regiments and the Divisions: specifically, that three regiments made up a ‘brigade’, and that each Division comprised around three such brigades.767 Precise organisational structures may therefore have varied between the Divisions. 5.3.3. Regional and guerrilla forces 245. Both the DK Constitution and the CPK Statute distinguished between three branches of the RAK: the “regular” forces, the “regional” or “Sector” forces and the “guerrilla” forces or “militia”.768 The evidence put before the Chamber did not clearly differentiate between the structure of the ‘regular’ and the ‘regional’ forces; however, it did establish that Sectors and Districts maintained their own military forces, separate from the Centre Divisions, primarily for the purpose of territorial defence.769 Moreover, even after POL Pot’s reorganisation of the military in 1975, some divisions remained under the direct control of Zone leaders.770 765 T. 9 January 2013 (UNG Ren), p. 57; T. 11 January 2013 (CHHAOM Se), pp. 75, 77; POL Nhan Interview Record, E3/5554, 31 August 2009, p. 5, ERN (En) 00377401; CHUM Cheat Interview Record, E3/5504, 8 October 2009, p. 3, ERN (En) 00398835; CHIN Kimthong Interview Record, E3/5512, 3 November 2009, p. 3, ERN (En) 00403579 . 766 T. 23 April 2013 (CHHOUK Rin), pp. 42, 56; T. 24 April 2013 (CHUON Thi), pp. 90-91; T. 2 May 2013 (LIM Sat), p. 68; Article by T.
