Timothy Knaggs (center), a team leader with India Company, 3rd Battalion, 3rd Marine Regiment, walks ahead of the Legged Squad Support System, acting as the "follow" for the machine at Marine Corps Training Area Bellows, June 19, 2014. The LS3 is designed to carry Marine's supplies like water, food and ammunition through rough terrain and is undergoing concept-based experimentation. The machine is operated with a Tactical Radio Control worn on the operator's back. The LS3 operates in three modes; Joystick Mode allows for manual operation with a handheld controller; Go-To Mode, in which the pilot sets a waypoint for the LS3 to travel to, and Follow Me Mode, where the machine uses sensors on the TRC to follow the operator.
