U.S. Navy Seabees and Marines work together to assemble a Medium Girder Bridge during a joint training exercise at Camp Lejeune, N.C. The Seabees, from the Naval Mobile Construction Battalion 133 Bridge Detachment, and the Marines, from the 8th Engineer Support Battalion Bridge Company, worked together for the first time on the three-day project, which built the MGB over a 107-foot-wide gap. The joint training, which was designed to build camaraderie and expose the Seabees and Marines to service differences, capitalized on Bold Alligator 2012, the largest amphibious exercise in 10 years.
