When you've heard that sound... or had one strike within inches of your noggin... (NOT a ND/AD)
It changes your outlook on life.
I've heard the sound my friend, just never while in the military.
I was a comms guy in the ARMY and mostly in fixed facilities inside the wire on bases both CONUS and OCONUS. The only time that changed was my last duty station, in which I had to wear a suit 95% of the time, stationed at Anacostia NAS with a secondary reporting station of the Old Executive Office Building.
