Gamani Samyuttam

Gamani Samyuttam; Some argue that a sutta in the Gamani Samyuttam rules out all military service. In this passage, a soldier asks the Buddha if it is true that, as he has been told, soldiers slain in battle are reborn in a heavenly realm. The Buddha reluctantly replies that if he is killed in battle while his mind is seized with the intention to kill, he will undergo an unpleasant rebirth.
