I am confused on who is using it and why. I have seen it on many post. Really, why? Who are you?
It was used on a post describing the marine corps culture having good camaraderie because their leaders (officers) look out for them and they are forced to rely on each other in training. An officer can’t make it through to become an officer if they are seen as looking out for themselves. They watch how they interact with others, and if they are not helping then they do not pass.
It also mentions why people don’t perform optimum on their jobs. The reason here was that their leaders and colleagues do not look out for them.
