Överfurir is an obsolete Swedish military rank established 1942 and placed above furir. Before 1972 the rank was a professional rank within the underbefäls category, and from 1972 to 1983 it was the highest rank within the gruppbefäls category. The holder of the rank typically served as instructor of conscripts corresponding to the present ranks of fänrik and löjtnant. A non-professional military service furir could obtain the rank through volunteer promotional courses within (FBU). It was removed as a professional rank in 1983, but appointments of non-professionals to the rank continued until 1991. Prior appointees retain their rank. Temporary appointments are still made in some circumstances, primarily for the duration of international peacekeeping missions. Police officers in international operations receive this rank to distinguish them from military police trained by the army.
