Which characteristic distinguishes medium machine guns from other types?

Medium machine guns are characterized by their ability to provide an effective balance between weight and firepower, making them versatile weapons on the battlefield. This balance allows infantry units to deploy these weapons in various roles without sacrificing maneuverability. They can be carried by soldiers, mounted on light vehicles, or used in a stationary position, adapting to the needs of different combat scenarios.

While other types of machine guns have specific traits, medium machine guns stand out due to their design which allows them to deliver sustained fire while still being portable enough for ground troops to transport and employ effectively. This feature is particularly important in modern warfare, where flexibility and the ability to respond quickly to enemy action can determine the success of a mission.
