US Army military mountaineering students build rope bridge
A U.S. Army Cpt. Andrew MacCornack (front) and Staff Sgt. Phillip Miller, both assigned to 5th Ranger Training Battalion, tie a rope to a tree while attempting to build a rope bridge over the Etowah River during the Basic Military Mountaineering Course at Camp Frank D. Merrill, Dahlonega, Ga., Jan. 21, 2016. The rope bridge is a "tight rope” or high load installation used to move personnel and equipment over terrain obstacles such as swift flowing mountain streams, ravines, and other deep gullies.
