Getting away from Scrotes like POTUS, I had the impression that this whole acronym thing was started by the US Military in WW2 (OOPS! another one slipped out)

I seem to remember things like SHAEF, SHAPE, COMSUBPAC, and CINCPAC.

May just have had summat to do with the need for brief radio communications.

More or less why we use IMHO, IMHO.
