when did the viet cong end? how did it end?
The Viet Cong were people. They didn't "end" unless you want to say that after the fall of Saigon in 1975, all Vietnamese were Vietnamese, no more north or south.

I'm not sure what you are asking. The Viet Cong were fighting units, so I am not sure what "it" refers to.
Since this is not my area of expertise, I searched Google under the key words "Viet Cong" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
The Viet Cong officially dissolved in 1976, following the end of the Vietnam War. However, it is important to note that the Viet Cong was not an official organization but rather a term used to describe the communist guerrilla forces in South Vietnam during the war.
The Vietnam War ended with the fall of Saigon, the capital of South Vietnam, to the North Vietnamese forces on April 30, 1975. This led to the reunification of Vietnam under communist rule. The North Vietnamese Army, along with the Viet Cong guerrillas, played a crucial role in the conflict's outcome.
To find this information, one can refer to various sources such as history books, articles, or reliable online platforms. Primary sources, including government records and firsthand accounts, can provide more detailed information on the specific dates and events surrounding the end of the Viet Cong and the Vietnam War.
