When were military vehicles used?

The first known use of military vehicles was in the 4th century BC when Alexander the Great used chariots armed with scythes in battle. However, the first major use of military vehicles occurred during the First World War when tanks and armored cars were used extensively. This was followed by the Second World War when a wide variety of military vehicles, including jeeps, trucks, and tanks, were used by all sides. Since then, military vehicles have been used in numerous conflicts and have become an essential part of modern warfare.
