Feldmarschall-leutnant

Lieutenant field marshal, also frequently historically field marshal lieutenant (German: Feldmarschall-Leutnant, formerly Feldmarschallleutnant, historically also Feldmarschall-Lieutenant and, in official Imperial and Royal Austrian army documents from 1867 always Feldmarschalleutnant, abbreviated FML), was a senior army rank in certain European armies of the 17th to 20th centuries. It emerged as the rank of field marshal (German: Feldmarschall) came to be used for the highest army commander in the 17th century (having originally been the equivalent of a cavalry colonel). In German-speaking countries the commander-in-chief usually appointed an "under marshal" (Untermarschall) or "lieutenant field marshal" to support and represent the field marshal. Amongst his functions as the personal deputy to the field marshal, were the supervision of supply depots and routes, and inspection of the guards.

The rank was used by the Imperial Army of the Holy Roman Empire from the 17th century until 1806. It was also introduced to the Army of the Austrian Empire in the period 1804 to 1866, and the Austro-Hungarian Army from 1867 to 1918, where it was the second highest general rank after the various heads of arm - the general of infantry, general of cavalry and general of artillery - until the introduction of the rank of colonel general in 1915. On the re-introduction of the rank of field marshal, it fell back to third place in terms of seniority.

Prince Montecuccoli, a field marshal himself in the Habsburg army gives the order of precedence in the Imperial Army as follows:

In 1789, for example, the Emperor conferred the rank of "Lieutenant Field Marshal on the Major Generals Count de Harrach, Baron d'Alvinzi, Prince Christian de Waldeck, Baron de Levenehr and Baron de Wallisch..."

Subsequently, the order of precedence of general ranks in the Austro-Hungarian Army was as follows:
