Ranks
Every soldier and officer of the Guard had the style of the Leib Guard (Лейб-гвардии ...), for example: Colonel of the Leib Guard (Лейб-гвардии полковник). It is a misconception that the monarch himself functioned as the commander of the Leib Guard regiments, so only he and some members of royal family could hold a title of Colonel (Polkovnik) of the Guards, but in fact there were many guards officers in the rank of colonel.
Commissioned officers enjoyed a two-grade elevation in the Table of Ranks over regular army officers; this later changed to a one-grade elevation -- first for the New Guards then for the rest of the Leib Guard. Following the abolition of the rank of Major in 1884, most grades below VII shifted one position upwards, effectively returning to those of the Old Guards.
