I don't see the "Destroy the Air Emplacement" mission as canon though. It's rather ridiculous to suggest that Cipher bombed the base to hide the fact that it was being used as a black site, and then the site ends up being rebuilt anyway.

But the op involving the JCS mole within the base who Snake interrogates to find the tape is real in my opinion. The tape acquired reveals background information on Skull Face, directly linking to the main story. This could still be a non-canon mission, simply designed to provide early life information for Skull Face, but who knows? Kojima has deliberately left them ambiguous to keep us guessing.
