Please, meet Captain Rabinovich Shmul-Izek Semenovich (b.1920). In service since 1938, when after graduating school he entered the Black Sea Higher Naval order of the Red Star Nakhimov School (ЧВВМУ). Graduated 15/Nov/1941.
Here is the hero in the centre as the Captain of the target ship "Цель" (Target), 1953. The identity is not 100% confirmed though... just 95% confirmed.

Note, that the order has been customised from medal-ribbon brooch to screw back.This was a common practice among naval personnel, pilots and tank troops. They found it to be more practical.
