Based on my research into the canon:
Richard/Jacket = Arrested
Tony = Died on May 5th
Dennis = Died on May 5th
Earl = Died on April 16th
Jones = Died on May 11th
Carl = Died on May 27th
Jake = Died on June 3rd
Richter = Arrested
Now, some theories:
Charlie and Biker are the same person. I believe that after Biker was beaten up by a Russian, he decided to wear more protection next time. After the events of 1989, Biker disappeared.
I don't believe Jacket's girlfriend is Don Juan, because that makes absolutely no sense. In his chapters, Biker encounters an operative wearing the pig mask (Aubrey). Yazter made a video about this, so I won't go into too much detail, other than to say Jacket's girlfriend/Aubrey = Dead; Don Juan = Probably disappeared out of fear after speaking with Biker.
Brandon is likely the Colonel of the Ghost Wolves; this isn't even really a theory. Brandon = Survived unscathed after the events of 1989.
I believe the "Innocent" campaign—which tells Nigel's story—is canon, simply because it's one of my favorite campaigns... Nigel = Survived unscathed after the events of 1989.
If you have anything to dispute or want to talk about another operative not mentioned here, feel free to do so.
