We never dealt with any UXO in the ER part of Bagram Hospital while I did my EMT-B clinicals there. Hell, we didn't even have a CT scanner, just regular old X-rays. From the picture of the actual round on the video it looks to be a 20mm projectile of some sort (or whatever the Soviet equivalent is,) I'd guess with an impact fuse. The soldier is apparently fine (well, aside from a bit of a nasty cut, cracked skull, and more than a little concussed...) That Purple Heart's coming with a pretty cool story though.
I give it a month before something like this is on House or the like.
