No matter how many people you kill, using a machine gun in battle is not a war crime because it does not cause unnecessary suffering; it simply performs its job horrifyingly well.

Soldiers join the military to serve their country, but when bullets are flying, it's hard to fight for an abstract notion like patriotism. They're fighting for the people standing next to them, and it doesn't matter who's a Republican or a Democrat, or who's black or white or Christian or Muslim or gay or straight. If Congress and all Americans could manage to ignore those differences, we would have a perfect country, but somehow we cannot rise to that level of nobility.

The Army might screw you and your girlfriend might dump you and the enemy might kill you, but the shared commitment to safeguard one another’s lives is unnegotiable and only deepens with time. The willingness to die for another person is a form of love that even religions fail to inspire, and the experience of it changes a person profoundly.
