What is the effective range of the M249 SAW in a sustained fire role?

The effective range of the M249 SAW (Squad Automatic Weapon) in a sustained fire role is approximately 800 meters. This range is determined based on the weapon's design and capabilities, which are optimized for providing suppressive fire while maintaining a manageable rate of fire. In the sustained fire role, the M249 is employed to deliver consistent fire over longer distances, making it an effective tool for infantry squads in combat scenarios.

The 800-meter range allows for effective engagement of enemy targets while taking into account factors such as ammunition temperature buildup and the need for barrel changes in prolonged engagements. This range supports the M249’s role in providing support to infantry units, enhancing their ability to cover ground and maneuver while keeping enemy forces at bay.

In contrast, other ranges listed in the choices do not accurately reflect the typical effective range for sustained fire. These provide different contexts for the weapon's usage in various roles, which may not align with the specific capabilities in a sustained fire context. Understanding the effective range is crucial for proper deployment tactics and maximizing the weapon's effectiveness in the field.
