Bringing light on this dead topic, I say Mercenary is the canon Ace Style.

Remember, Pops was ordered to drop a nuke and he refused, so he fled to B7R where he was pursued by Schwarze. From there, we see Bernitz show up and shoot down both Bartlett and Pops. As Sly said before, this is all supported by AC5.

The reason I believe that the Soldier is non-canon is because we never hear anything about Heimeroth's involvement in the Belkan War in AC5 other than the fact that he was "there". Same goes for Riedel in AC6, his Assault Record doesn't state anything about his engagement in B7R with Cipher.

The reason Knight isn't canon is because we never hear anything about it in other games.
