In accordance with the federal law of December 8, 1997 "On Immortalizing the Soviet People’s Victory in the Great Patriotic War of 1941–1945", the regiment also maintains a guard of honor (Russian: Почётный караул) at the eternal flame of the Tomb of the Unknown Soldier.

In September 1918, the Latvian Riflemen left for the fronts of the Civil War, and they were replaced by the officer cadets of the 1st WPKA Soviet Joint Military School "All-Russian Central Executive Committee" that were redeployed into the Kremlin for this purpose.

In 1973 the unit was renamed the Separate Red Banner Kremlin Regiment, later receiving an Order of the October Revolution.

Before being deprived of Mausoleum guard duties in 1993 as a result of the collapse of the Soviet Union and the constitutional crisis of that year, the regiment finally received its current designation in accordance with a presidential decree of March 20 that year, this time under the Federal Protective Service.

Since 1997 the Kremlin Regiment has resumed guard duties by presidential decree on the Tomb of the Unknown Soldier and its Eternal Flame, keeping alive the legacy of those who served on the Eastern Front.

Starting in 2004 a Guard Mounting ceremony has been held on Cathedral Square on Sundays, from March to October.

Around that time it also acquired special ceremonial uniforms closely modeled on those worn on parade by the infantry and the cavalry of the Russian Imperial Guard until 1914.

These are worn in addition to modern style dress uniforms adapted from those utilised during the Soviet period.

Uniforms based on the ones used by the infantry of the Regiment during the Second World War were worn for the first time by a platoon from the 1st Honor Guard Company during the 2015 Spasskaya Tower Military Music Festival and Tattoo.

The cavalry escort takes part in the Russian presidential inauguration, as well as the Moscow Victory Day Parade on Red Square.

In addition, since 2004, the cavalry has been participating in the changing of the guard on Cathedral Square and annually performs a demonstration program at the races for the President's Prize.
