Marines with Bridge Company, 7th Engineer Support Battalion,

Marines with Bridge Company, 7th Engineer Support Battalion, 1st Marine Logistics Group, secure an Improved Ribbon Bridge, to extract it from the Colorado River, during a training exercise in Laughlin, Nev., March 17-21, 2014. More than 60 Marines trained in moving heavy equipment, to include 7-tons and Humvees, across a flowing body of water using BEBs and an Improved Ribbon Bridge. The IRB is a multi-piece floating bridge that can function as a raft. The BEBs were used to push the raft against the current. Despite being accustomed to training in a bay with little to no current, these Marines managed to transport two 7-tons up the river at the same time.
