Marines have an attitude that they are best in the world and look down their noses at the other branches.

Perhaps. It is true that the Marines are a pretty confident bunch. I've experienced the "we're the best" attitude in all the services

I think you'll find that *any* group that large will have its share of elitist snobs. The ex-Marines I know are the complete opposite of attitude. Granted, I don't know how they view the other branches of the service, but I'd take that all with a grain of salt -- everyone has their inter-whatever rivalries: my school's better than yours; my country's better than yours; my team's better than yours; etc.

I say be a Marine -- you get a cool sword!
