U.S. Air Force Capt. Chad Willis, 35th Aerospace Medical Squadron optometrist, pulls out a game piece from the game "Operation" during a 35th Medical Group warrior medic challenge at Misawa Air Base, Japan, Aug. 17, 2012. Airmen had to pull out six pieces to move to the next station, and if the game buzzed, they had to do three burpies. To boost morale, four squadrons from the 35 MDG showcased their fitness skills to see who would dominate the competition. (U.S. Air Force photo/Airman 1st Class Kia Atkins)
