Stabskapitän

Stabskapitän (English: staff captain), in the cavalry also Stabsrittmeister ("staff riding master" or "staff cavalry master"), or Kapitänleutnant (captain lieutenant), was a historic military rank in the Prussian Army.

Its holder represented the actual captain and company commander in his absence, frequently and often for long periods, should his (usually noble) Hauptmann show no interest in leading the company, though the Hauptmann would retain his rank, status and uniform.

In the army of Frederick the Great, a regiment's regimentschef, oberst, staff officers, company commanders and those of nearby rank received a far higher rank than the staff captains who actually led the company.

A similar rank, was stabskapten (Swedish), or alikapteeni (Finnish) in the Military of the Grand Duchy of Finland, using the Russian rank system (see below).

Shtabs-kapitan (Russian: штабс-капитан) was in the Russian Imperial Army (RIA) until 1917 a light captain rank (NATO-equivalent OF-2b) who was in charge of a company-size military unit.
