The Defense Department has released its top picks for the most memorable images of 2012.
The more than 40 images include U.S. soldiers, jets and other military machinery, amputees, citizens in foreign countries and stray dogs. While some of the images call for laughter and awe, others call for sorrow and solemn reflection.
The images were chosen as winners, runners up and honorable mentions for the department's Visual Information Awards Program in seven categories: Operational Combat, Combat Training, Hardware, News Photography, Pictorial, Portrait and Sports.
The program is 'designed to recognize, reward and promote excellence among military photographers, videographers, journalists, broadcasters, photojournalists, graphic artists and mass communication specialists for their achievements in furthering the objectives of military photography, videography, and graphic arts,' according to a Defense Department release.
Below are select photos from the department's picks for last years' most visually striking military moments (not in order of ranking).
