Last but not least to the subject or Russian naval infantry [Marines].
To reiterate Coastal Troops [CT's] consisting of * Coastal artillery * Coastal anti-ship missiles * Naval Infantry [Marines].
Naval infantry an integral part of Russian Coast Troops [CT's].
Naval infantry [Marines] primarily regimental sized units but according to the Soviet defector Suvorov. also found at brigade level under certain specific circumstance. During that Soviet era each fleet [Northern/Baltic/Pacific/Black Sea] having an organic regiment of naval infantry.
Each regiment having an entire combined arms capacity minus organic aviation assets:

A regiment of naval infantry that correct mix of combat arms elements to include infantry, tank multiple-rocket-launcher, anti-tank and air defense.
Again, from Suvorov naval infantry in the Soviet/Russian model not always merely a regimental sized unit:
"The Soviet Navy has only brigade of marine infantry. This belongs to the Pacific Fleet. It consists of two tank five motor-rufle battalions and is equipped with especially heavy artillery."
Once more and in finality from Suvorov as to the recognized fighting capacity of naval infantry:
"Generals from the Land Forces who have watched exercises carried out by the marine infantry often say, with some envy, that a regiment of marine infantry, with the same equipment as that issued to the Land Forces, is the equivalent in its operational potential of one of the latter-s motor-rifle divisions."

Count naval infantry among those CT's soon to be deployed to the Pacific coast of Russia? I think so.
