Located in Oslo, the force has responsibility for the whole country, including oil installations in the North Sea. Beredskapstroppen took part in the dramatic hostage situation at Sandefjord Airport on September 29, 1994. Delta is similar to FBI Hostage Rescue Team in the United States. Unlike the rest of Norwegian Police, they are routinely armed, weapons including Glock 17 pistols and MP5 submachine guns.
Beredskapstroppen spend 50 % of their time training and preparing for missions, and the rest of the time they normally work like ordinary law enforcement in Oslo. For training in close quarters combat they often use a specially built city inside Rena military camp close to Rena which originally was built for training the Telemark Battalion and other military special forces.
One of Beredskapstroppen most dramatic missions was the Torp hostage crisis. Where an elderly couple and two police officers were taken hostages by two foreigners. In the end of the two day drama, Beredskapstroppen executed a rescue operation rescuing all of the hostages and killing one hostage taker and arresting the other.
Since October 2006, Delta has focused their operations against gang crime in the capital of Oslo and arrested many criminals and seized many weapons used by the gangs.
Members of Beredskapstroppen has also been deployed in Special Team Six. (See below)
Beredskapstroppen has got two Rigid-hulled inflatable boats. Both of them has got three engines with a total of 675 HP. When it comes to air transport, Beredskapstroppen uses military Bell 412 SP from the RNoAF. The operators use a special type of visor on their helmets which can withstand 9mm bullets. Other units using this visor type is French GIGN. The unit uses a gas mask with a closed system (rebreather). They also used advanced equipment to determine the type of chemicals they are up against with. They wear slightly different uniforms, instead of the normal black pants and blue shirts they wear black jumpsuits and often, but not always, drive an unmarked Chevrolet Suburban. These Suburbans are very easy to spot because of a large firetruck ladder on the roof.
