Yes, most definitely. All of the photos on Department of Defense websites are taken by military photographers. Check out the DefenseLink website http://www.defenselink.mil/multimedia/ for some incredible pictures from them.
Are civilian photographers also referred to as combat photographers?
Yes, they are. The designation 'combat' has to do with the type of photography they are doing. Some of the most memorable photographs from our past wars have been done by civilians. For example the D-Day photographs of Robert Capa and the pictures of the fighting in Hue during the Vietnam War taken by Don McCullin.
Those images are awesome!! Everyone should go take a look.
