Third Arm is another ambitious project of the US Army, the goal of which is to create a "third arm" for the soldier, with which he can more evenly distribute the weight of heavy weapons, reducing physical activity.
The predecessor of the Third Arm is the M56 Smartgun, an additional mount for the MG-42 machine gun. Mechanical Engineer Dan Bachel has developed a more advanced version capable of taking the weight of a weapon from a soldier's hands. The Third Arm is a composite hinged frame that evenly distributes the weight of the weapon and allows for effective use of its capabilities on the battlefield.
According to lead researcher Dan Bachel, the “third hand” is still in the prototype stage and is constantly being improved. The device is part of the army's modernization program, which includes many exoskeletal developments.
