I've got a bunch of good grades at A-Level, but I'm looking to go in as a Marine. I'd hope to work my way up to Sergeant level. I just like the idea of being an NCO... you know, having authority over the men but still able to be 'mates', well more so than an officer would be able. At the moment, I'd be far more interested in leading a section in a firefight than being more 'stand-offish' as an officer should be... Both jobs are equally important, but I just prefer the first.
As for the whole money thing, at this moment in time I'd do the job for room and board - I don't have any plans for marriage, or kids. That may change... but at the moment I'm a millitant bachelor.
How come you don't see yourself beyond Sergeant? Or do you mean do 10-12 years and then leave?
