I don't think those are CRADLE agents actually. From what little we've seen from them they have mostly non-lethal weaponry, and what looks to be advanced riot gear, with helmets and shields and such. Also, I can't see the cradle insignia anywhere on their persons but that just might be due to the artist. If I had to guess I would think these were a bunch of bad guys who may have tried to use the "dragon" for some evil plot the Champions had to stop.
Also since it's Marvel, C.R.A.D.L.E. may very well be an acronym for a longer name similar to S.H.I.E.L.D. or S.W.O.R.D.; anyone wants to take any guesses of what the full name of the organization is?
