Don't forget the American obsession with militaristic technical jargon and acronyms/backronyms. There's a normal word for most of those guys in actual English.
G I z z o - It's not so much American English, it is the military/Department of Defense jargon.
Remember SCUBA? It was a dad in my old neighborhood who worked as a civilian engineer in the WW2 time and later. The navy developed the 'frog man'. A lot of engineers worked on the project. But, it was my neighbor who created the acronym self contained underwater breathing apparatus.
It's more a of military thing, not a civilian thing. But, in a neighborhood like mine, military personal were mixed in with the rest of the community.
Maybe it's the media that makes it seem like acronyms are more common than they are.
