Napalm became an intrinsic element of US military action during the Vietnam War as forces made increasing use of it for its tactical and psychological effects. Reportedly about (388,000 short tons; ) of US napalm bombs were dropped in the region between 1963 and 1973, compared to (32,357 short tons; ) used over three years in the Korean War, and (16,500 short tons; ) dropped on Japan in 1945. The US Air Force and US Navy used napalm with great effect against all kinds of targets, such as troops, tanks, buildings, jungles, and even railroad tunnels. The effect was not always purely physical as napalm had psychological effects on the enemy as well.
