There are lots of other awards for heroism. Anyone with a CIB is a hero in my book. But the MOH is by definition for those that went 'above and beyond." The consequences of going above and beyond in modern warfare is more likely than not, a posthumous award.
Like the Purple Heart, the MOH has become one of those medals that you don't want to receive.
Why would anyone want to be in a position to want a bronze or silver star? I'd steer well clear of anyone psycho enough to have any of those as an objective.
Excellent post.
