John Wood, 841st Transportation Battalion, 597th Transportation Brigade security coordinator, directs vehicles with generators onto Military Sealift Command’s USNS Brittin at Joint Base Charleston Naval Weapons Station, S.C., Oct. 28, 2017. Joint Base Charleston was chosen as a central hub for Hurricane Maria relief efforts because it’s one of the few Department of Defense installations with both sea and aerial port facilities.
