Our Company Commander was great. There wasn't a man in the company who wouldn't have walked through fire for him. Oh, I grumbled and griped like the rest of them. But when I got out of boot camp, I was in the best shape I've ever been in. And I had learned how to obey, with pride.
Obedience is necessary.
Especially in the military. It wouldn't do to have everyone in the company questioning the orders of the Commanding Officer in a critical maneuver. If you didn't it could cost you your life and maybe the lives of others. But you don't have to come back. That's the essence of obedience.
