The M739 Light Machine Gun, also known as the SAW (Squad Automatic Weapon), is used in heavy engagements where sustained or suppressive fire is required.



  • The SAW is powerful enough to take down most enemies in just a small burst.
  • The SAW has a large magazine.


  • The SAW recoils a player's aim upwards as it fires.
  • The SAW has a long reload time.
  • The SAW is ineffective at long range.

  • The SAW's damage has been increased to maintain double the damage-per-second of the Assault rifle.

Changes from Halo 4 to Halo 5: GuardiansEdit

  • Slightly higher rate of fire.


  • The SAW has a holographic ammunition indicator bar on the back of its top rail. As the ammunition in the magazine is used, the bar depletes and changes color from yellow to red.
