I'll look into these more, but my first response is beware of people who can brag up on some sort of secret training they received that just happens to make their book or movie (or maybe even video game) that much more interesting or purchasable.
That's so true i seriously doubt that actual agents who were in the field and very successful would tell anyone that they were agents. Isn't that like committing suicide in the spy world? Also i believe that the spy world isn't as glamorous as the movies and video game makes them out to be, because in the real spy world behaving like James bond can get u killed easily. Real spies would most likely recruit from their enemies and have them do all the leg work and try fade out in the crowd. But i guess real spy work doesn't translate well into exciting movies and games. I also think the reason the for the stereotyping of spies being like james, or jason is because of all the secrecy its more fun to imagine spy work being exciting like in the movies.
With all that in mind i can see from a developers or movie maker's prospective why actual CQC would not translate to well to seem exciting in a game they dont have the impact. So picking an art appears a little flashier would be a good thing but dont make it too over the top
