I have a few questions regarding to the killing of "the enemy" during combat. Users who've served in the Military would probably consider these questions basic. At any rate, here goes:
If you shoot at the enemy and incapacitate them to where they can no longer fight, are you obligated to finish them off, or do you seek medical attention and take them prisoner (assuming the situation allows)?
Are you obligated to kill an unarmed enemy soldier if they don't surrender?
Are you obligated to kill enemy soldiers who are unarmed, have not surrendered, but are totally trapped/surrounded (example -- a bunch of enemy troops are out of ammo, but holed up in a small dead-end cave.... your squad/unit/whatever is at the entrance of the cave......do you toss in tear gas, or start spraying napalm?
How do you handle a situation where the enemy's weapons are absurdly inferior to your own military?
Let's say an imaginary new tribe was discovered in a remote jungle. The tribe's chief declares war, and the 'warriors' of the tribe are armed with nothing but spears and clubs. They are all dedicated soldiers who will fight to the death no matter what, and never surrender - even when taken prisoner. Do you kill them, or do you use modern nonlethal riot control tactics (tear gas, high pressure hose, etc).
1. It's you obligation to ensure enemies can't get back up to fight again or make a report. Kill them. Especially if saving them is going to be a burden. It's easy. Either slit their throat or shoot them in the head. I would rather save ammunition so if finishing them off with a knife is possible, I would do just that.
2. If they don't surrender then their only option is death.
3. If they are unarmed and are already outmanoeuvre by the squad then they can be POW. They better hope the Geneva Conventions apply to where's they're off to. Hahaha...
4. If they have been known to never surrender the best thing to do is to exterminate them in the most efficient way posible to cut cost, time, and loss of lives on our side. Naturally there will obviously be an attempt at negotiation first with terms of surrender offer and such. If they they are willing to fight to the finish then they must be destroyed right down to the very root. They are a threat as long as they exist especially if there's no evidence of them ever submitting to anyone before. Any survivors are potential terrorist/future enemy in the making. Plenty of historical examples if you care to look it up.
