The old guard/agent model was the GIGN model from CS 1.6?

So, i was playing CS the other day, when i decided to choose the GIGN class. I looked at his face, then i noticed something familiar.
Due to my habit of explore game files, audio and textures, i've reached the guard texture/model, so i easily felt something was familiar.
Here is a screenshot:
