Just found out about CS:2

And from the looks of it, It hasn't come out yet

(correct me on that if I'm wrong)

If it isn't out, they should re-add the Spetsnaz, and maybe add a Mexican marine team, that would be cool to see, (even though mexico has drug cartels and not terrorists)

Other teams could be:

CIA Special Actions

Delta Force

KSK (as a team for multiplayer)

If you have any other unit suggestions, comment it
