The oddest thing is that the human being, the soldier is the cheapest part of the war. I think the droids will not be used because that would be a waste of money whereas you can get 'gun food' more cheaply. For ammo I think the idea to make more wounded than dead is 'the idea'. A wounded person takes two soldiers with him to take away from the battle scene, a dead soldier perhaps none. I recall that in the Iraq-Iran war the latter used teenagers to discover mine fields. They walked in bigger groups and they had been given a plastic key around their neck ' made in China' that would open the heaven's door... what utter ×××××!
