Note that we were working with the Navy when I was at that defense contractor!
They even had the term "NAVSEARS" which was... (wait for it...) a Sears catalog! SMH! 🤷♂️
When I was contracted to a defense contractor back in the 1980's, I was the guy who compiled and distributed the list of abbreviation definitions! Heck, they even had abbreviations where some of the letters were additional abbreviations! SMH... 🤷♂️
