ソン・セン
By 1972 Son Sen had become Chief of Staff of the Khmer Rouge forces. Despite occasional criticisms – his colleagues found his style peremptory and his point of view "bourgeois", and he was openly criticised by Hou Yuon at the Party's 1971 Congress – his devotion to Saloth Sar and his closeness to the Party 'Centre' guaranteed his senior position.
