I mean, yes, obviously it's not literally the Arecibo telescope in the same location, but it's a heavy inspiration and quite similar in design and structure. (For example, an obvious difference in BF4 is the surrounding forest, which not as dense as in Puerto Rico's location.)

I would say it takes inspiration from Arecibo over FAST but it's clearly neither. The surrounding topology is flat in comparison to either and there isn't much of a forest to speak of. It's clearly a level design that takes inspiration from reality.

Correct! I did not mean to say that it was actually Arecibo in a different country, but rather that it was fairly heavily inspired by it.

I mentioned some of what you talk about in the latter part of your comment in another reply on a descendant of the GGP.
