You’re probably familiar with most of the celebrities who will be competing on the 13th season of Dancing with the Stars (after all, David Arquette, Ricki Lake, and Nancy Grace are all big names), but there’s one person you might not be as familiar with –All My Children actor J.R. Martinez.

So to save you the trouble of googling him (you know you will), here’s some background on him.

Martinez, 28, is an Iraq war vet who was badly injured after the Humvee he was driving hit a land mine while deployed with the Army in Iraq in 2003.
