ABERDEEN PROVING GROUND, Md. -- When engineers from the U.S. Army Research Laboratory brainstormed on how to improve Soldier lethality, the idea of a third arm seemed like something that might help. Mechanical engineer Dan Baechle carefully planned out a device that doesn't need batteries, is lightweight and can evenly distribute the load of a heavy weapon. "It can help stabilize the weapon and take the load off of their arms," he said. "It's made from composite materials to make it as light as possible, but also to ensure the range of motion that Soldiers need." The device, officially called the Third Arm helps take the weight of the weapons off of a Soldiers' arms. It weighs less than four pounds, and because of the innovative design, the weight of the device and the weapon are evenly distributed. "We've actually tested it with the M249 and M240B machines guns.
