LoveUniHateExams confessed, "...I wouldn't enlist - I don't think I'm brave enough."
Don't make the mistake of thinking that everyone who serves is on the front line being RAMBO.
Although everyone does have to pass basic training and learn the fundamentals of war-fighting, think about all the SUPPORT that those guys on the front line need. SOMEBODY has to be "brave enough" to provide that support.
Are you "brave enough" to run around a track? "Brave enough" to do pushups and pullups? "Brave enough" to learn how to shoot? "Brave enough" to continue your education in a way University can't match? "Brave enough" to cook decent meals for your troops? "Brave enough" to repair a broken Humvee? If you are really sharp, you might be "brave enough" to translate enemy communications, or "brave enough" to be a drone operator sitting somewhere in Kansas.
I think you get my point... And in the unlikely (but possible) chance that your support position is overrun and you find the lives of yourself and your buddies at risk, you will find that you ARE "Brave enough"! Your training will kick in and you will fight for the lives of yourself and your team.
Remember that whether you are brave or not, there is an "expiration date" on your life, just as there is on mine. Be "brave enough" to live your life with pride.
