Yesterday I watched a movie on the ScyFY channel titled "Sunshine" were a group of astronauts go to the Sun on a mission to fix a problem with it in order to save the Human race. Long story short it turns into a suicide mission for one of the characters. Sorry if that spoils it for you. In the military, we don't have "suicide missions" because that goes against most religious ethics. Instead, we have "high risk" missions. As long as there is an 'out', a measly 1% chance of survival, then, buy definition, it isn't a "suicide mission". When I was a Naval Aviator, our operating bible was the OPNAVINST 3710. It's about an inch and a half thick but does include this short paragraph: There are numerous reasons to use operational necessity in wartime, but peacetime missions are usually only associated with rescue operations. The main purpose of this thread is to discuss the ethics of a suicide or "high risk" mission and under what circumstances, if any, members of the forum would consider undertaking such a task.
