The Army Ranger Battalion (ArmÃ©ns jÃ¤garbataljon, AJB), also known by its old name Norrland’s Dragoons or K 4 is a detachment of Norrbotten Regiment (I 19) and has its base in Arvidsjaur, in the Norrbotten County of Sweden. The Army Ranger Battalion is an elite light infantry unit trained to carry out reconnaissance missions and direct action behind enemy lines. Anyone qualified for military service can apply for selection at the Army Ranger Battalion. After the general 3 month long basic training (GMU), several tests, both physical and psychological are conducted over a period of days. If the candidate is successful, he/she will begin the roughly 12 month long basic ranger course. Upon completion of the course with satisfying results the candidate will be awarded with the Ranger tab and posted to one of the battalion’s two Ranger squadrons. Since 2007 the battalion also has a mountain leader platoon which specialises in operations in and around mountainous and alpine terrain. This platoon has been of much use in Afghanistan since a lot of weapons, drugs and the like are smuggled high up in the mountains in Afghanistan. The mountain leader platoon has also been involved in search and rescue operations domestically, such as the 2012 Norwegian C-130 crash. Members of the unit have served in Bosnia, Kosovo, Afghanistan and Mali.
