That's a 105mm artillery shell. And for some reason the kid in the back is wearing a Turkish hat. The ones around are wearing the traditional Afghani hat, yet it is also worn by Kurds in Iran/Iraq/Turkey.
So if I were a betting man it wasn't from Pakistan, but either Northern Iraq or Afghanistan.
That is a pic of a Predator Drone carring the Hellfire missile. Up close picture is..
Thus... it could not be from the Predator. And I would be willing to bet it wasn't even in Pakistan. Anyone for strike three?
