I seem to recall that during the Civil War, 600 Confederate officers were held as POWs and used as human shields. They became known as The Immortal 600. Perhaps we should use these Iranians in a similar manner. Make them walk ahead of military convoys, or send them in first when doing searches to see if a place is booby-trapped or not. I'm not well-versed in todays' military tactics or procedures, but it seems they could be used somewhere as human shields.
"Make them walk ahead of military convoys"
I liked the Spartan decision in "300", to use them as morter for their wall.
