SNAFU, made me recall MFWIC... Mo-Fo What's In Charge!
Near 30 years in the Forces, I learned a LONG time ago, that trying to carry over 'known' acronyms from one section or branch, NEVER worked out while trying to translate anything written by someone in another field of expertise! At least the technical manuals actually has a glossary in the back that clarified and standardized WHAT each particular 2, 3, 4, 5, 6, or 7 letter acronym actually referred to!
Much like the engine room comment earlier on in this thread, inside of closed groups, one tends to forget that outside of those groups, the same acronyms can have entirely different, and often enough, baffling, meanings.
