If we start to travel from the Mississippi River westwards to the Pacific Coast, than the starting point is a lowland, vast one, as we continue to go towards the west we will encounter high mountains, the Rocky Mountains more specifically, and the elevation will go up to 4,400 meters above sea level, than we will go down, elevation wise, to the high plateaus and will be on elevations between 1,000 and 2,000 meters, and after we go up again to almost 4,400 meters as we cross the Cascade Mountains. After the Cascades we go gradually downwards towards the lowlands, where we will first go a bit bellow sea level, and than little up in the lowlands along the Pacific Coast, and at the end reach a point of zero elevation.
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. In this war the Republic of Vietnam (South Vietnam) participated, which was against the communists, with the support of the United States and other allied nations of the United States against the local guerrillas of the National Front for the Liberation of Vietnam ( Viet Cong) and the Army of the Democratic Republic of Vietnam (North Vietnam), backed by China and the Soviet Union.
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.
