Arméns Jägarbataljon

Arméns Jägarbataljon, AJB, (in English, the Army Ranger battalion) also known by its old name Norrlands Dragoner or K4 is a detachment of Norrbotten Regiment, I19 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.

Since 2007 the battalion also has a mountain leader platoon which specializes in operations in and around mountain passes. This platoon has been of much use in Afghanistan since a lot of weapons, drugs and such get smuggled high up in the mountains in Afghanistan.

Members of the unit have served in Bosnia, Kosovo and Afghanistan.
