"Which brings me back to where I began. Those of us who’ve been sent here to serve can learn from the service of our troops. When you put on that uniform, it doesn’t matter if you’re black or white; Asian or Latino; conservative or liberal; rich or poor; gay or straight. When you’re marching into battle, you look out for the person next to you, or the mission fails. When you’re in the thick of the fight, you rise or fall as one unit, serving one Nation, leaving no one behind"
