Does the word "to" initial count in an acryonm. Words like "of" I see aren't used like in FBI but the would you use the initial for "to" in an acryonm. Having a brain fart...
I've seen it used in the initialism RTFM.... can't recall being aware of it in an acronym. For that I'd say leave it out.
It depends how cool the acronym sounds with or without the little words. FBI sounds cool. FBOI would sound stupid. And all the government shit is three letters. I think it's in the Constitution... somewhere at the bottom.
I'd tend to think nah, but if you want to include it to make the acronym cooler, go for it. NASA comes to mind for acronyms that are a little silly explained but sound cool shortened (OSIRIS Rex was the specific one I remembered: Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer), so that's for sure something that happens in real life.
