Matthew Callahan

The change for U.S. Marine Matthew Callahan came when he "snapped" his leg.

It was his first deployment to Afghanistan with 2nd Battalion, 3rd Marine Regiment. He was an "assaultman," a Marine specialized in assaulting hardened positions.

He was sent to the Wounded Warrior Battalion to recover, where he picked up a camera and started On-The-Job Training (OJT) to be a combat correspondent.

"I feel being a former infantryman gives me a better perspective and will serve me well in telling the stories of Marines from the ground combat element especially. Civilians have a genuine interest in knowing about the ins and outs of Marine life and I have a genuine desire to tell them. It's incredibly satisfying and a wicked good time," Callahan told Business Insider.
