Marshal of the Russian Federation
Marshal of the Russian Federation is the highest rank of the Russian Federation, created in 1991 after the fall and breakup of the Soviet Union. It ranks immediately above the General of the Army and Admiral of the Fleet.
The only officer who presently holds the rank is the former Minister of Defense Igor Sergeyev, who was elevated from the General of the Army of the Military Space Troops. Since Russian military ranks system lack a brigade-grade general but has a General of the Army, a Marshal of the Russian Federation should be considered as a honorary title equivalent to a Field Marshal or General of the Army in other countries, created in the vent of a major war or as the result of extreme military accomplishment.
Confusingly, there's no rank similar to the Admiral of the Fleet of the Soviet Union, so Marshal is a supreme rank for both army and naval officers.
The insignia for Marshal of the Russian Federation is similar to the one for the Marshal of the Soviet Union, with Soviet Coat of Arms replaced by a Russian one.
