A large ocean-going tug boat assigned to the 7th Transportation Brigade (Expeditionary) returns to Third Port at Fort Eustis, Va., Jan. 5, 2015, after being displaced for two years. The boat was allowed to return after a month-long dredging process was recently completed at Third Port, clearing the waters of build up sediments.
