Sure enough, I looked it up, and found these.The MTF units are nearly exactly the same as the GIGN soldier from Counter Strike: Source. If you look closely, you can see there is no GIGN badge on their shoulder. But the clothing is nearly the same as the GIGN in CSS
I'm sure its a coincidence, but I feel this is a bit too close for comfort. They seem to be based of the same model, and they both have the same shade of indigo for their uniforms.
My decision for an alternate color scheme would be one of these two of the original guard models.

I think the orange and white/black color scheme would suit the Nine Tailed Foxes, as it suits their image more.
