Semper Fidelis

If one serves in the US Army, fights valiantly in wartime, but returns home to abuse drugs and alcohol to the point of homelessless, no longer contributing to the betterment of his society, but often scaring others with his profuse uses of profanity and ill-motor control, then he is no longer a man to be admired. By the same token, if one becomes a US Navy officer or Marine Corps infantryman, and serves his four years with or without a scuffle, then over the course of the next several becomes a bitter reflection of those ideals he was so intensely taught, then the old honor no longer applies.

I always felt and taught that a true warrior follows the Warriors' code of ethics, which includes faithfulness to the cause, including intense bravery where one in four are certain to freeze-up, to never surrender and to never leave a fellow warrior behind.  It means dying for a set of values that are highly set, by the very best.  It doesn't mean a perfect soldier; read of Sir Gawain and the Green Knight; read Rudyard Kipling.  It's clear that to his best moral integrity is what a true soldier must remain ever faithful.
