I disagree, tight cohesion is important for any position in the military. When you are in a combat situation where you are responsible for the life of yourself and the lives of others then it doesn't matter what unit you are in. You could be the cook and you are in the same situation as the SEALS right next to you. That's what military training is all about, right from basic training. You learn to think and act as one so that everyone is on the same page in any given situation. Special forces just gets a lot more of this type of training and it's more intense. Regular units are the punch clockers of the military, the special forces are more like the startups.
