Fortified Hamlets
Fortified Hamlets are communities of people who live in Vietnam. These are the people that the United States are trying to protect from the North. The United States would start at one town and move through each town. The idea was to train the people who lived in those towns how to fight if the North Vietnamese were going to come through.
Having trained people wh o can fight off the North Vietnamese help tremendously for the United States. This made it so we wouldn't have to come and rescue the towns that had been attacked. This way we could focus on the bigger problems in the war. This was a part of the Vietnam War.
