Airmen from the 386th Expeditionary Logistics Readiness Squadron Aerial Port use muscle power to push a pallet of cargo onto a C-17 Globemaster III at an undisclosed air base here Nov. 3, 2010. Known informally as “Port Dogs,” Aerial port airmen inspect and palletize all cargo before shipment, from food and water to ammunition and rolling stock. They also work closely with aircraft loadmasters to carefully position the cargo inside aircraft, loading it into planes with massive forklifts or special flat-bed trucks known as K-loaders.
