I recall when I was promoted to Sergeant. I was fresh out of the Airborne Regiment, somewhat "cocky" (OK - I had an ego that couldn't fit into a C17).
Concurrent with my promotion came a posting to an air force outfit. I got all dressed up in my best short-sleeved DEU (we had the tans back then), placing my ribbons on my chest, and my fresh new metal rank insignia on my collar. I put on my gleaming dress boots, complete with clickers, and reported to work.
I walked into the hangar showing attitude that Chuck Norris would have admired - click ... click ... click.
Some greasy old fart dressed in coveralls appeared in my field of view - yelling something about getting out of "his" hangar with those clickers and all that "FOD".
"Who the hell are YOU?" I inquired.
"I'm the SWO" was the reply.
"What the hell is a SWO, and while we're at it - what the f*** is FOD?"
A passing SAR Tech (with whom I had served prior to his remuster) rescued me.
The clickers were removed fairly rapidly - I became intimately acquainted with what a "SWO" is - and a compromise was reached on the "FOD" dripping off my Army uniform.
