Accuracy Under Fire ( A.U.FIRE )

LAPD Officer Tim Pearce founded Accuracy Under Fire (A.U.FIRE) after his wife, Officer Kristina Ripatti, was shot and paralyzed in the line of duty. This tragedy led to lifesaving training technology, inspired by the TENS unit, a muscle-stimulation physical therapy device used for Kristina. Accuracy Under Fire repurposed that technology to deliver advanced haptic feedback that simulates injuries, enhancing realism in police and military force-on-force training. Our system uses wearable TENS unit (E-stim) sleeves that enable instructors to remotely contract limb muscles, instantly simulating the intense incapacitation caused by gunshot wounds or limb injuries in the heat of battle. This injury simulator's immediate feedback delivers real consequences, pushing trainees to handle extreme stress, maintain tactical accuracy, and solve problems under pressure in real time. It allows them to practice fighting back accurately and effectively while injured, providing invaluable training experience before it happens in real life. A.U.FIRE fosters stress inoculation and a survival mindset, while providing crucial experience in weapon handling, accurate return fire, and tourniquet application under critical conditions—preparing officers and warfighters to perform confidently in a crisis.
