U.S. Soldiers, Marines, Airmen and civilian contractors push equipment into the cargo bay of a C-17 Globemaster III, assigned to the 816th Expeditionary Airlift Squadron, at Al Asad Air Base, Iraq Jan. 25, 2018. The C-17 transported troops and equipment to forward operating locations throughout the U.S. Central Command area of responsibility in support of Operation Freedom’s Sentinel and NATO Resolute Support missions. The C-17 is not only proficient in transporting troops and cargo, but can perform tactical airlift and airdrop missions and transport ambulatory patients during aeromedical evacuations.
