Marine Corps Weapon Systems: M249
The M-249 Squad Automatic Weapon (SAW) is a great weapon and the key component of a fire team. It enables a fire team to quickly and effectively gain fire superiority. The SAW is light and maneuverable, but it packs enough punch to suppress the enemy and provide cover fire for fellow fire team members. Marines will learn and practice with this weapon while at the School of Infantry (SOI). Some Marines may be issued the M-249 upon reporting to their unit. They are called automatic riflemen. Ordinarily, there is one automatic rifleman in each Marine Corps fire team, but it is vital that each member of the team be familiar with the weapon.
