The Department of Defense has just announced the top military photos of 2013, arranged in six categories: Afghanistan, Defense Leaders, Operations/ Training, Disaster Response, Warrior Games, Military Life.

We’ll be posting them all here, but naturally will start with Afghanistan. These are remarkable photos taken by talented photographers, a few of whom I know personally from my time as a Marine Corps combat correspondent. They also showcase the remarkable service and skill set of those who executed year 12 of one of the most complex wars in American history.

Here are the photos:
