# Oberstleutnant

Oberstleutnant (German pronunciation:) (English: Lieutenant Colonel) is a senior field officer rank in several German-speaking and Scandinavian countries, equivalent to lieutenant colonel. It is currently used by both the ground and air forces of Austria, Germany, Switzerland, Denmark, and Norway. The Swedish rank överstelöjtnant is a direct translation, as is the Finnish rank everstiluutnantti.

## Austria

Austria's armed forces, the Bundesheer, uses the rank Oberstleutnant as its sixth-highest officer rank. Like in Germany and Switzerland, Oberstleutnants are above Majors and below Obersts. The term also finds usage with the Austrian Bundespolizei (federal police force) and Justizwache (prison guards corps). These two organizations are civilian in nature, but their ranks are nonetheless structured in a military fashion.

## Germany

Typically, suffixes can be applied to the word Oberstleutnant to specify the individual type of officer. Retired officers that are not incapacitated (i.e. theoretically available for reactivation) from service continue to use their title with the suffix a.D. (Germany) or aD (Switzerland), an abbreviation of außer Dienst, 'out of service'. Suffixes that specify military specialization in active service include Oberstleutnant i.G. ('im Generalstabsdienst') for general staff officers or Oberstleutnant d.R. ('der Reserve') for reservists. The suffix i.R. ('im Ruhestand'), implying retirement without the legal specification of a.D., is unofficial.

### Bundeswehr

The armed forces of West Germany and unified Germany since 1955, the Bundeswehr uses the Oberstleutnant rank in the German Army and German Air Force. Equivalents in the other branches are Fregattenkapitän for the German Navy, Oberfeldarzt for medical staff, Flottillenarzt for naval medical staff, Oberfeldapotheker for apothecary staff, Flottillenapotheker for naval apothecary staff, and Oberfeldveterinär for veterinary medical staff.
Within the German state employee paygrade system, the Oberstleutnant is placed within Besoldungsgruppe A and receives either the A14 or A15 paygrades, depending on individual seniority. Thus, the Oberstleutnant is paid an equivalent wage to that of first-class consuls and legates in the foreign service (A14) or state-employed school directors, ambassadors and general consuls (A15).
The age limit for Oberstleutnant-rank officers is 61.
The Oberstleutnant's shoulder straps in Army and Air Force are marked by two vertically aligned stars above oak leaves.

### Bundesgrenzschutz

The Federal Border Guard (Bundesgrenzschutz) used the rank Oberstleutnant until 1976, after which it was replaced by the terms Polizeioberrat and Polizeidirektor as part of the government's effort to transform West Germany's federal border guard agency into a less militarized structure.

### Wehrmacht and Waffen-SS

The Wehrmacht (1935-1945) of Nazi Germany used the rank of Oberstleutnant for Army and Air Force, much in the same style the Bundeswehr does. The Waffen-SS (1933-1945) used the rank Obersturmbannführer as an equivalent.

### Nationale Volksarmee (NVA)

The National People's Army (1956-1990) of East Germany used the rank Oberstleutnant (abbr. OSL) for its army and air force, whereas the Volksmarine used the term Fregattenkapitän.

## Norway

The rank of Oberstløytnant was introduced around the same time as Denmark, as Norway at the time was part of Denmark–Norway.
