An Airmen from the 15th Airlift Squadron, assigned to Joint Base Charleston, South Carolina, helps chain down a Hard-side Expandable Light Air-Mobile Shelter (HELAMS) belonging to the 621st Contingency Response Wing, onto a Globemaster III C-17, also from JB Charleston, Sept. 29, 2014. The HELAMS will be used by the 621st CRW in West Africa in support of Operation UNITED ASSISTANCE in response to the Ebola virus disease outbreak. The CRW is highly-specialized in training and rapidly deploying personnel to quickly open airfields and establish, expand, sustain, and coordinate air mobility operations. From wartime taskings to disaster relief, the CRW extends Air Mobility Command's reach in deploying people and equipment around the globe. (U.S. Air Force photo/Staff Sgt. Gustavo Gonzalez)
