What is a key characteristic of air-cooled machine guns?

Air-cooled machine guns are characterized by their lighter weight and design for enhanced mobility, which makes them highly effective for various tactical scenarios. This design typically includes a barrel that radiates heat away from the gun during operation, allowing for a simpler construction without the extra weight of a water cooling system. The emphasis on mobility allows operators to carry these weapons into diverse terrains or situations, making them a preferred choice in situations where quick maneuverability is crucial.

This characteristic is particularly advantageous in combat situations where the ability to reposition quickly can provide a tactical edge, such as during infantry or ground operations. The lighter weight also contributes to less fatigue for the operator, allowing for sustained use during engagements without significant strain.
