Ringerike Army (Ringerike Hær)

Consisting of the full-time Army and the part time volunteer reserve the army is responsible for ground based warfare, and also maintaining a limited organic aviation capability. The majority of infantry regiments contains multiple regular and reserve battalions. Modern infantry have diverse capabilities and this is reflected in the varied roles assigned to them. There are six operational roles that infantry battalions can fulfil: Parachute infantry, air assault, armoured infantry, mechanised infantry, mountain infantry and light role infantry. Some units also perform specialist secondary duties, such as 33 Mountain Jeger Regiment (33. Fjelljegerregiment), which provides a national mountain rescue service. Regiments and battalions e.g.: the Life Guards Regiment, exist within every corps of the Army, functioning as administrative or tactical formations.

Arms and support units are also formed into similar collectives organised around specific purposes, such as the Corps of Engineers and the Logistics Corps.
