It's T99. T99 seems to have slightly more tan in it since it was designed to be used by peacekeepers in the African theater. M/01 seems to have slightly more red in it and as McNair said, it has sleeve pockets with velcro, (which that one appears not to have). M/01 is only issued to soldiers going to Afghanistan, all other troops serving elsewhere are issued temperate M84. Both are still in use because of limited production numbers, but M/01 is becoming much more common because the army has been adopting Crye-produced combat suits in it.
That being said, it is literally impossible to get anywhere, even in Denmark since it is only issued to troops actually going to deployment and none of it is taken out of circulation.
