The importance of hand-to-hand combat in major militaries has declined since World War II. This is due to the development of advanced weapons, such as drones, and a focus on other combat techniques.

Vietnam, in many ways, is an example of this. The war's goal was not geographical; instead, it was simply “body count.” The focus was on the number of dead bodies. Often faces were not always seen.

Bombs and even infantry fire were focused on where the enemy might be.

The United States dropped 8 million tons of bombs on Indochina between 1962 and 1973, compared with a total of around 4 million tons dropped by all the warring nations in the Second World War.
