Military working dog Jimo and handler Senior Airman Alex MacMillan, 75th Security Forces, pose next to a Quad-legged Unmanned Ground Vehicle, also known as a robot dog, Aug. 24, 2021, at Hill Air Force Base, Utah. The purpose of the Q-UGV won't be to replace MWD's but to enhance security to the base allowing defenders to patrol and monitor more critical areas. (U.S. Air Force photo by Cynthia Griggs)
