M-EDF 9/21/1

"Hard-ass grunts."

- Staff Sergeant Avery J. Johnson describing M-EDF 9/21/1 .

M-EDF 9/21/1, or Ninth Marine Expeditionary Force, 21st Division, 1st Battalion, was a part of the 9th UNSC Marine Corps Expeditionary Force assigned to the Eridanus System.

In 2513, it was commanded by Lieutenant Colonel Ponder, and had an operation at Elysium City, Eridanus II. M-EDF 9/21/1 was ordered by FLEETCOM to neutralize the second-in-command to the Insurrectionist leader, Colonel Robert Watts. Against FLEETCOM's insistence on a show of force, Ponder attempted to personally speak to family members of the second-in-command, when a M-EDF 9/21/1 sharpshooter took a hasty shot, completely collapsing the situation. As a result, Ponder was demoted to the rank of Captain and reassigned from M-EDF 9/21/1.
