Soviet Naval Infantry

[Raellus]

In the Soviet Vehicle Guide, four regiments of Naval Infantry are listed. None of those are identified as being based in Sevastopol, or operating anywhere in the Black Sea region during the war.

According to current sources, there were four brigades in the late 1980s, one of which, the 810th, was based in Sevastopol. The existence of a Soviet Naval Infantry unit in the Black Sea region was known (or at least strongly suspected) during the Cold War. Osprey's Warsaw Pact Elite Forces (1985) places an unidentified Guards Naval Infantry Regiment there.

Have any of you seen mention of Soviet Naval Infantry in the Black Sea region during the Twilight War (in any canonical source)?

I suppose the Black Sea-based unit could have been destroyed, or absorbed by another unit, but the SVG usually mentions stuff like that.

Also, aside from the landings in Alaska, does cannon mention any other Soviet amphibious operations anywhere?

Thanks.
