I just stumbled upon this trailer, then proceeded to buy the movie through iTunes. While watching, I wondered whether these guys were GIGN, but for whatever reason the script did not want to use “GIGN.” Well, at the end, it became apparent that they were pre-GIGN, and that their unit later became the GIGN.
OOPS! Wrong link. Give me a moment...
OK, trying again:
Edited to add: I remember when this original incident occurred, and also remember reading a quite good narrative of it, later, but cannot recall whether I read a book, or a very good, in-depth article. That was the day when one could still buy truly informative magazines.
