Vietnam War also called Second War of Indochina, was a war fought between 1955 and 1975 to prevent the reunification of Vietnam under a socialist or communist government.

The battles that took place during the conflict occupied the entire territory of Vietnam, the main characteristic of these battles is that they occurred in an area of dense forests, full of natural elements and animals that made the operation of the army of the USA difficult. We could say that this factor greatly favored the army of North Vietnam, since they knew the battlefield perfectly.
