HBP, the word "Romeo" has been used in the past (and still is used today) in the maritime industry phraseology to denote an "affirmative" answer to either an instruction or otherwise. The word "roger" (or "rodger" as some purists may insist - me not being one of them), has been used in Nautical terms for quite a long while (it's origins pre-date me, that is...), however on a more practical note, this has slowly been changing back to "roger", at least as far as boats go.
Another useless speck from the mine of information.
