The Finnish Border Guard, under the ministry of interior, has renamed its Sissi companies to Border Jaeger companies and has adopted the term (Special) Border Jaeger as a replacement for the term Sissi. These units are trained to operate behind the enemy lines with asymmetric tactics and unconventional weapons and methods as well as to conduct long term operational reconnaissance and aggressive short term reconnaissance and sabotage. Aside from classical Sissi training, the training also includes peacetime operational methods and the responsibilities of the Border Guard i.e. border control, patrol, and tracking and catching illegal intruders.
