Other Soviet Books:
The Soviet Soldier 1941-1945 by Philippe Rio – A good reference for the uniform and equipment used by the Soviet army in WWII. There may be a very few minor mistakes, but overall a solid reference.
Why Stalin’s Soldiers Fought by Roger R. Reese – A study of the human side of the Soviet army and the motivations of it’s soldiers.
When Titans Clashed by David Glantz and Jonathan House – David Glantz has written many books about the Soviets and WWII, but this appears to be a compact, overall look at how the Soviets took on Germany. If you like this book, it might be good to look at some of the other things Glantz has written.
Bloodlands by Timothy Snyder – This book covers the huge amounts of death and killing that occurred in the areas of the Eastern Front, between the Soviet Union and Nazi Germany. A sobering reminder of the ugliest parts of WWII.
