The M-47 is a main battle tank that was developed in the early 1950s by the United States. It was designed to replace the M-46 tank and was widely used during the Cold War. The M-47 features a 105mm gun and has a fully rotating turret, allowing it to engage targets effectively from various angles. This tank was used by several countries and saw action in various conflicts, including the Vietnam War. The M-47 was eventually succeeded by more advanced tanks, such as the M-60, but it remains an important part of military history.
