By the way according to Ed Maier only 22 Navy DSM's were awarded to Soviets.
According to OMSA article only 20 (Army?) DSM's were awarded to Soviets.
Dave Danner wrote in this thread http://gmic.co.uk/index.php/topic/8433-us-army-decorations-awarded-to-red-army-personnel-in-world-war-ii/ (post #15) that "During World War Two, the Army awarded approximately 9 DSMs to lieutenant colonels, 2 to majors and 2 to enlisted".
So how many DSMs (Army and Navy) were issued?
