The Special Operations Command (SOKOM) is the overall command for Denmark's special operations forces that consist of three units: the Sirius Dog Sled Patrol, the Danish Army Special Forces Jaeger Corps (JGK) and the Danish Navy Special Forces, the Forgman Corps (FKP). More recently SOKOM has established, “Arctic Specialists”, which complement and expand Denmark’s Arctic capabilities in Greenland.

Now former members of the Sirius Patrol have been recruited into a new highly mobile capability designed to supplement the existing sled patrols. The unit employs snowmobiles and fast boats and can be deployed by aircraft or air-dropped by parachute.

The Arctic Specialists (ARK SPEC) are, like the Sirius Patrol, organized under the Sirius Squadron within the Danish Army Special Forces (Jægerkorpset). Unlike the Sirius Patrol, ARK SPEC does not use sled dogs but instead snowmobiles, fast motorboats and other mobile platforms. ARK SPEC and its equipment can also be deployed by air or air-dropped by parachute.

The new capability is composed of former Sirius personnel who have undergone additional training. Among other qualifications, they have received alpine and glacier climbing training to operate in high-mountain terrain and glacier areas, skills not included in the standard training for Sirius Patrol leaders. One advantage of recruiting former Sirius members is the ability to build on the extensive experience they gained during their two-year patrol service. Another is that the new specialists will carry out many of the same tasks but at significantly higher tempo.

The primary mission is to support the Joint Arctic Command in SAR operations in terrain that is normally inaccessible. Another key task is reconnaissance, monitoring areas to identify persons or activities that should not be present. A third important task is recovery operations.
