In a ski hutte in south Germany, bunch of enlisted who are looking after relaxing seniors in the eve, hard day skiing, few beers underway. Equivalent of SAC promoted - unknown to most - approached by 4* SACEUR USA and 4* DSACEUR GE who slap his new rank slides on each shoulder simultaneously - observed by, and timing called out, by 4* Chief of Staff at SHAPE UK ...! A 12* promotion - lovely look on his face and nicely done.......
Nicely done, indeed...my promotion to Cpl was marked by the Sqn and Flt Cdrs simultaneously applying my new rank slides to my wooly pully (yes, I was inhabiting it at the time!). Nowhere near what this chap got, but recognition all the same, and I've remembered it to this day.
