I admit it’s real-world uses may be a little limited, but it’s good fun as an educational “toy” for anyone learning the phonetic alphabet.
I’ve also put up a copy of a picture alphabet sheet I created which may be useful as well. The clipart looks a bit 1990s, but that’s because I created it a long time ago.
I’ll add some more information in the future. Somewhere I have some information and handouts I put together in the past for radio communications training.
