Describe how the Vietcong fought against the American and south Vietnamese forces.

The Vietnamese Communists, or Vietcong, were the military branch of the National Liberation Front (NLF). Other needs were met inside South Vietnam. Main force Vietcong units were uniformed, full-time soldiers, and were used to launch large scale offensives over a wide area. Regional forces were also full-time, but operated only within their own districts. When necessary, small regional units would unite for large scale attacks. If enemy pressure became too great, they would break down into smaller units and scatter. Unlike the main troops, who saw themselves as professional soldiers, local Vietcong groups tended to be far less confident. For the most part, recruits were young teenagers, and while many were motivated by idealism, others had been pressured or shamed into joining. They also harbored real doubts about their ability to fight heavily armed and well-trained American soldiers. Initially, local guerrillas were given only a basic minimum of infantry training, but if they were recruited to a main force unit, they could receive up to a month of advanced instruction. Additionally, there were dozens of hidden centers all over South Vietnam for squad and platoon leader, weapons and radio training. To ensure that the guerrillas understood why they were fighting, all training courses included political instruction.
