If I get you correctly another re-phrasing could be: If we put a human soldier into a situation that is dicey, like a mix of civilians and terrorists we didn't expect, we are obligated to get that human out even if it risks more soldiers and local civilians. But if we put a drone in the same dicey situation we can just accept the loss of that drone and self destruct it without harming any soldiers or civilians.
