U.S. Army tugboats come alongside the USNS Mendonca at the Port of Tacoma, Wash., March 17, 2014. Soldiers assigned to the 7th Transportation Brigade, an active Army unit from Fort Eustis, Va., and the 385th Transportation Battalion, a U.S. Army Reserve unit from Tacoma, Wash., were loading the tugboats on board the Mendonca. The vessels are on their way to Alaska to take part in Joint Logistics Over the Shore 2014, an annual exercise designed to test logistics capabilities across a broad spectrum. (U.S. Army photo by Lt.
