Christopher Lawley, 28th Munitions Squadron mission systems technicians, align strakes on a Mark-84 inert bomb during training in the conventional maintenance shop at Ellsworth Air Force Base, S.D., Nov. 7, 2012. The strakes increase the distance and accuracy of the bomb, and provide the precision necessary to hit the desired target. (U.S. Air Force photo by Airman 1st Class Kate Thornton-Maurer/Released)
