Defence Navy — deck personnel Federal Security Service Coast Guard of the Border Service of FSB National Guard National Guard Naval Service Corps The highest troop rank is Marshal of the Russian Federation. The highest Navy 'deck' rank is Admiral of the Fleet. In the Soviet era the rank Admiral of the Fleet of the Soviet Union was equivalent to the rank of Marshal and only three persons were given that rank. Since 1991 this rank is no longer used. Ranks can have additional descriptors according to assignment or status. For example, the rank of a serviceman of a "Guards" unit, formation or ship may be followed by the word "Guards" ("Gefreitor of Guards"); the rank of a serviceman of the legal, medical or veterinary professions is followed by "of Justice", "of the Medical service", or "of the Veterinary service" ("Captain of the Medical Service"); and the rank of a reserve or retired serviceman is followed by the words “Reserve” or “Retired,” respectively ("Major of Reserve").

Note: the descriptor "of Aviation" has been officially abolished but usage is still common within the Air Force and Naval Aviation.

WO's and Officer ranks received updated shoulder rank epaulettes (and for the Navy, cuff rank insignia) and all General Officer and Flag Officer rank insignia now reflecting service affiliation in the duty dress uniform (the old pattern epaulettes were replaced by the army green, aerospace forces blue and navy blue epaulettes (duty dress depending on service) and gold (parade dress) epaulettes similar to those used in the mid 1970s by the Soviet Armed Forces). This was also the case for the Marshal of the Russian Federation rank epaulette, which still retained the Coat of arms of Russia and the Marshal's Star. But this change is now evident in the battle dress and duty uniforms only, in
