Politiets Aktionsstyrke (AKS, English: The Special Intervention Unit) is the police tactical unit of the Danish National Police. It is meant to handle extraordinarily difficult or life-threatening criminal situations, such as terrorism, hostage situations, and kidnapping. It also deals with emergency rescue situations that would be too dangerous for others to handle. The AKS holds responsibility for all anti-terror and counter-terrorism missions in Denmark. It is known that AKS cross-trains with the army and navy elite-units Jægerkorpset and Frømandskorpset.Their training includes: tactical shooting, hand-to-hand combat, surveillance, and explosives. Policemen who want to join the unit are required to take and pass selection tests.
