Corporal Cody Burris, left, a 22-year-old of Amelia, Ohio, and Sgt. Rodney Gleisner, right, a 28-year-old of Watertown, N.Y., both maintenance mechanics, Maintenance Detachment, Combat Logistics Battalion 15, 1st Marine Logistics Group, repair a Humvee during the battalion's first field training exercise of the year at Red Beach aboard Camp Pendleton, Calif., May 6-10, in preparation for pre-deployment training with the 15th Marine Expeditionary Unit this fall. The exercise allowed CLB-15 to practice procedures and protocols they will apply while acting the 15th MEU's primary logistical support element during its deployment early next year. Providing this support to the MEU allows it to focus on its chief objective as a crisis response force, ready to respond to disaster or humanitarian relief operations.
