Forsvarets Spesial Kommando - FSK (The Special command of the army) is another special forces branch in Norway.
These guys are trained for anti-terrorist actions such as hijacked airplanes, hijacked cruise-ships, hijacked oilrigs and other situations.
They are equiped with the best available equipement, stuff that you'd only dream of or use while playing ActionQuake 2.
The personel of Forsvarets Spesial Kommando are trained as attack-divers, paratroopers, and the usual special forces stuff such as close quarters combat, survival in extreme situations and alike.
The weapon of choice in this branch is the Heckler & Coch MP5, but this may vary.
