Once a soldier, always a soldier.
It's an amazing experience to become a soldier, even to just complete initial training. Your level of confidence rises, and something in you "grows up." At least that's what my experience was. There are so many things the average person doesn't realize is drilled into a soldier, and this is clear evidence of those things being under the surface, even after years of adjusting to civilian way of life. There's no turning back.
