Spc. Hilda I. Clayton US Army

The Army has released an image taken by a combat photographer moments before she was killed in an explosion during a 2013 live-fire training exercise in eastern Afghanistan.

Spc. Hilda I. Clayton, a visual information specialist assigned to the 55th Signal Company (Combat Camera), was killed while photographing a live-fire training exercise on July 2 in Laghman Province. Four Afghan National Army soldiers were also killed when a mortar tube accidentally exploded.

One of the Afghan soldiers killed was a photojournalist whom Clayton had been training.

The primary mission of Combat Camera soldiers is to accompany soldiers on deployments to document the history of combat operations.

"Clayton's death symbolizes how female soldiers are increasingly exposed to hazardous situations in training and in combat on par with their male counterparts," the Army said in a statement.

Clayton's name has since been added to the Defense Information School Hall of Heroes at Fort Meade. The award for the winner of Combat Camera's annual competition was also named after her.

"The Spc. Hilda I. Clayton Best Combat Camera (COMCAM) Competition consists of five days of events to test joint service combat camera personnel on their physical and technical skills," the Army said.

Here are the images the Army released:
