M274 Mechanical Mule - A History 

The M274 Mule was a four-wheeled, lightweight utility vehicle used by the United States military in the Vietnam War. It was designed to transport troops, supplies, and weapons in rugged terrain, and it became an important part of American operations in the conflict. The Mule was equipped with a small cargo bed and had the ability to carry a variety of weapons, making it a versatile tool for soldiers in the field. Despite its usefulness, the Mule had several limitations, including a lack of armor and poor off-road capabilities. Nevertheless, it remained in service with the U.S. military until the 1980s and is remembered as an iconic symbol of the Vietnam War.
