Currently, he serves as the First Sergeant for Hammer Company, 1st Battalion, 17th Infantry Regiment, 2d Stryker Brigade Combat Team, 2d Infantry Division at Joint Base Lewis-McChord, WA. Mackie has served in Korea, Ft. Carson, CO, Schofield Barracks, HI, twice in Afghanistan, and twice in Iraq accumulating over 59 months of overseas service.
