You know , the whole prisoners of war thing is kind of a recent idea.For thousands of years the defeated were killed or enslaved. Since Arafat and his people can't seem to keep their word or refrain from disguising murderers as police what would you all suggest ? Remember these are the guys who were actively trying to kill you a moment ago,but they surrendered (or did they?)so be nice !
In one of the Dorsai novels (if memory serves) there is a war with mercenaries involved. ANyway the usual way is to accept the surrender of opposing forces who are fleeing , surprised in bunkers, etc. But the guy who fires a handheld missile at you , misses, and THEN tries to surrender....
