Darrell Rusk provided this photo today of his son, Marine Pfc. Colton Rusk, with Eli, a black Labrador being retired from military service following the death of the younger Rusk. Colton's parents are adopting the bomb-sniffing dog who the military says loyally rushed to their son's side when he was fatally shot. The 20-year-old Texan died in December during a gun battle with Taliban fighters. (AP Photo/courtesty of Darrell Rusk)

DFO: This is a heart-breaking photo. It makes me think of my niece, a lieutenant in the Army National Guard, who just returned to the Middle East for her second tour of duty. She was deployed in Afghanistan first. Now, she's in Iraq. Sometimes, we forget that many families still have loved ones in harm's way.

Question: Do you have a loved one currently deployed in either Afghanistan or Iraq?
