The military is even worse. I once attended a high level classified briefing at Patterson AFB. Lots of generals and other senior officers. I could not understand half of what they were talking about because of all the acronym. Might as well been in a foreign language.
During one of the breaks I mentioned it to one of the junior officers. A short time later he handed me a two page cheat sheet with all the acronyms explained so I could follow the briefing.
I guess I was not the first to mention the problem.
I saw the same thing in the private sector in commercial mortgage banking.
All newbies were handed a glossary of terms as part of the on-boarding process.
It ran about ten pages single spaced—hundreds of terms and acronyms.
Every sector speaks its own language in this highly specialized world.
