It was actually Sniper Jesus that was apparently inserted into the chain of command at a Fort Bragg unit.
I still think this was a real photo (the shadow is consistent, albeit from a smaller frame). However, I doubt that this picture would fly very long. It was probably either somebody goofing around, or otherwise trolling. That’s why I crowdsourced the verification. Good eye, commenters / Facebook
If you know what unit this came from please contact me. I just want to verify that this was a joke. You never know with Poe.
