The unit is located in Sodankylä and Rovaniemi in Finnish Lapland, some 130 kilometres (81 mi) north of the Arctic Circle.

[2] The Jaeger Brigade specialises in training soldiers for the harsh climate of Lapland.

Their expertise in cold-weather warfare is widely recognized; members of the U.S. and other militaries come to Sodankylä in winter to learn from them.

In 1944, following the Continuation War, this unit became the 1st Battalion of Air Defence Regiment 2.

In 1967, the unit received the provincial name of Ostrobothnia Air Defence Battalion (Finnish: Pohjanmaan Ilmatorjuntapatteristo), which was changed to the current name in 1974.
