This is part of a eighteen-part series, about The Great Patriotic war, as Russia's fight against the Germans in World War II was known. There are lots of amazing facts, information about how they fought, Stalingrad, Leningrad, and many other places. Weapons used, tanks, aircraft types, etc. It is in Russian with English subtitles, you can slow down the speed in the settings to be able to read the subtitles easier . . . this is an amazing documentary, I am currently watching it for the third time.
