What is the main function of the M249 Squad Automatic Weapon (SAW)?

The M249 Squad Automatic Weapon (SAW) is primarily designed to provide suppressive fire, which is essential for enabling maneuverability and control on the battlefield. Suppressive fire helps to keep the enemy pinned down, thereby limiting their ability to return fire or maneuver effectively. This capability allows infantry squads to advance or reposition without facing immediate threats.

The weapon's light machine gun design allows for sustained fire with a high rate of ammunition feed, further enhancing its role in providing ongoing support to infantry units during combat operations. The M249 can be deployed from a bipod in various combat situations, delivering effective firepower while still being portable enough for squad-level operations. This versatility makes it a critical asset for maintaining operational tempo and gaining battlefield advantage.

The other options do not accurately represent the primary role of the M249, as it is not utilized as a sniper rifle, not designed to act as a grenade launcher, nor is it primarily meant for vehicle support. Instead, its focused capability as a suppressive fire platform underscores its importance in infantry tactics.
