PFC Marcus Beedle leads the mule-like robot known as the Legged Squad Support System on a patrol through open terrain at Fort Devens Mass. Beedle, working with other Marines from 1st Battalion, 5th Marine Regiment learned how to control LS3 and work it into basic formations and maneuvers during the limited technical assessment at Fort Devens. This was the first time Marines have been given control of LS3 since the Warfighting Lab began working with the Defense Advanced Research Projects Agency (DARPA) and the system's developer Boston Dynamics. The Warfighting Lab is working with the DARPA and Boston Dynamics to explore concepts that can potentially lighten the load of Marine units. LS3, still in the early stages of development, is capable of carrying 400 pounds of gear and traversing terrain that wheeled and tracked vehicles cannot. (Official USMC Photo by Kyle J. O. Olson)
