U.S. Soldiers assigned to the 689th Rapid Port Opening Element run to avoid the rotor wash of a CH-47 Chinook after conducting a sling-load at Fort Eustis, Va., March 24, 2016. The RPOE practiced several iterations of sling-loading cargo containers and vehicles as a way to master the skill that is vital to contingencies involving closed roadways.
