I don't know. As I said I hear rumors a lot. Unlike the Army and marines though, the navy doesn't go on land and fight. Unless you are in the seals. They usually just transport, and have the ships with all the weapons and what not.
I'll have to agree with this, when you join the military you definitely realise that you could be sent to war, and that could be a war that you don't agree with. However, it seems to me unlikely that anyone who would join the military would find any war unjust. Killers aren't very rational. Sorry, but if you're going to soak the gov. for "school loans" and other benefits, you have to pay your dues....don't give me this "oh, I didn't think I'd actually have to go to war !!! I thought I could just take tax dollars and get free school and travel!"
