Behind all the "motivation" and "Hoorah" is a service with a very different philisophy. That means always doing things on the cheap, generally crappy living conditions and a much more intrusive way of interacting with its members lives. If that sounds like fun to you, then have at it.
Different philisophy is 100% right. Marines act different overall, and are certainly treated different. Some might say worse. It is a bit of a badge of pride, though. I loved asbestos filled, moldy, waaay overfilled barracks. I tried to explain our living conditions as Officers to some AF and even Navy guys and they basically thougth I was lying to make Marines sound tough. I got a kick out of that.
If you are a Marine going to a Navy or army, or AF, or whatever base for the first time, stand by for some serious culture shock. My idea of military (before and after entering the service) was very different from what I saw there.
