Viet Cong
The group was made up of people from both South and North Vietnam. Most of the people in the group were communists but some members were not communists, but the main leaders were. The Viet Cong used guerilla warfare, including terrorist bombings, assassinations, and ambushes. The group is best known for the Tet Offensive, a surprise attack on many South Vietnamese cities that began in January 1968 during Tet, or the Vietnamese New Year. The group was closely allied with the government of North Vietnam, which conquered the South in 1975.
