It's not just a mantra, I promise you.

"Every ranger, and there are more than 2,000 of them, says a six stanza Range creed, you may know one life of it and they say I'll never leave a fallen comrade to fall into the hands of the enemy. And it's not a mindless mantra, and it's not a poem.  It's a promise. Every Ranger promises every other Ranger, no matter what happens, no matter what it costs me, if you need me, I'm coming." [Watch Video on YouTube]
