Senior Airman Nick Lodge, 811th Security Forces Squadron response force member, performs a pullup as part of a security forces defender competition on Joint Base Andrews, Md., July 23, 2018. Lodge, along with other defenders, fought for one of the four positions on the team going to Camp Bullis, San Antonio, Texas, to represent the Air Force District of Washington in the Defender Challenge 2018. The challenge will give the Air Force and partnering allies such as the Royal Air Force, the German Luftwaffe, the Royal Australian Air Force and the Royal Canadian Air Force a way to showcase their military police capabilities and joint interoperability. It is the first time the competition will be held since 2003. (U.S. Air Force photo by Airman 1st Class Michael S. Murphy)
