Brian Grady, 27th Special Operations Support Squadron range support operations planning specialist, tests the power mechanism of a simulated improvised explosive device at Cannon Air Force Base, N.M., Sep. 9, 2019. Improvised explosive devices are a large threat to our military overseas, so our combat training element team at the Monster Garage has many models and iterations of IEDs they use to keep our Airmen on our range alert to potential sources of danger that could cause real-life harm in a combat situation.
