No one knows where it comes from.
Why some have it and some don’t.
It’s the fighting spirit. And it needs to be fed. It consumes fear, self-doubt and weakness.
It stands ready to protect those in danger and to fight whatever shape the battle takes.
For Marines, the fighting spirit burns bright long past service, because as long as there are battles that need to be won, there will always be Marines.(DoD video)
