Completely serious, thanks. It is totally normal for the Marines to beat it into you, they are trying to make sure that when the shit hits the fan you do what you need to do without hesitation.

Yes, I was in the U.S. military 25 years ago. I will leave it at that and not try to demean your opinions with an unnecessary personal attack. It's just the Internet, after all, and 'winning' an Internet argument ain't worth it ;-).
