Kneeling in the foreground of this photo, within the overhang of several trees, a camouflaged soldier with a green beret and a rifle strapped across his shoulders crouches, an affectionate grin creasing his unshaven face.
With its broad paws placed within the man's lap, a large German shepherd wearing a Kevlar harness nuzzles against the soldier's chest, the dog cuddling within the military man's arms while its jaws are clamped about a bundle of ragged cloth.
After some scrutiny, you deduce it to have once been the bloodied crotch of a very unfortunate pair of trousers.
In recent penmanship, someone's jotted on the photo's rear.

"I'm sorry."
