However, I feel that service is more than to your branch, commander, or unit. What is a soldier? Someone willing to sacrifice themselves for a greater, to defend those who can't defend themselves, to bring honor to their service. A US soldier serves the people first, the government second. Manning realized the risk he was placing his life in, and like a true soldier, he didn't let that knowledge deter him. In taking responsibility, he's holding his head high, not cowering behind attorneys and HTTP proxies.
I can't say if he's right or wrong, but I can say that he showed courage befitting his title.
