 In this case, and I have talked about this scenario before any number of times about a soldier jumping on a grenade to save his fellow soldiers from an explosion. You're right, that is heroic. You and I don't disagree on that at all. And it's not really a gray area at all, honestly, for a soldier to jump on a grenade to save his fellows. It's not suicide, strictly speaking. It amounts to knowing that he would die.
