Mao era

Since the 1950s, Pol Pot had made frequent visits to the People's Republic of China, where he received political and military training�"especially on the theory of the dictatorship of the proletariat�"from the personnel of the CCP. From November 1965 to February 1966, high-ranking CCP officials such as Chen Boda and Zhang Chunqiao trained him on topics such as the communist revolution in China, class conflicts, Communist International, etc. Pol Pot also met with other officials, including Deng Xiaoping and Peng Zhen. He was particularly impressed by Kang Sheng's lecture on how to conduct a political purge.

Recruits: The term used to describe new soldiers.

Entrenchments: Long cuts (trenches) dug out of the earth with the dirt piled up into a mound in front; used for defense.

Kepi: (pronounced KEH-peeh) Cap worn by Civil War soldiers; more prevalent among Union soldiers.

Flank: Used as a noun, a "flank" is the end (or side) of a military position, also called a "wing". An unprotected flank is "in the air", while a protected flank is a "refused flank". Used as a verb, "to flank" is to move around and gain the side of an enemy position, avoiding a frontal assault.

Havelock: (pronounced hav-loc) A white cloth cover that went over a soldier's kepi, and had a long back that covered a soldier's neck and shoulders. Although it saw use in the early stages of the war, soldiers quickly learned that it cut off circulation around the head and face, leading to the eventual abandonment of the havelock.
