Where do Medics fall under? They are Military, but they are not technically soldiers and they are required to treat casualties on both sides. I remember during World War 2 how the Quakers managed to combine their pacifism with their anti-Axis powers messages by encouraging their members to enlist as medics. Several received the Medal of Honour, especially those who went to the Pacific, where the Japanese targeted medics and even chaplains.
Trying to enforce today's generation is useless since once developed, people rarely change the ways of their upbringings. but educating the next generation and insuring we teach them -how- to think and not -what- to think, will be the solution in my opinion.
