Who is Viktor Petkov from Ice Hunt and what is their importance?

An Admiral, Viktor wears a long greatcoat with a fur cap. There are red epaulets on the caps' front and four gold stars. He smokes Cuban cigars, and has a commanding presence. Viktor has storm gray eyes and is only a year from retirement. Now, he can hardly remember being as young as the Captain is now. Viktor is tall for a submariner, and his frame is lean and lanky. His head of hair is white which along with his demeanor has earned him the nickname of the 'White Ghost' (Beliy Prizak).
