Now their are only 3 explanations for this either
1: the Russians where incredibly incompetent which i reject since the red army through leaderless in the early days was still a well trained professional force
2: the Germans had Superhuman abilities . Which i reject as well. They had more experience and better leaders at first but it still shouldn't explain the 1:3 ratio
3: or their was something wrong with the soviet tanks.
4: Lack of training for the crews.
5: Lack of infantry support in the early tank brigades.
6: Poor composition in tank brigades 1941-42. (When T-70, T-26s, T-34 and KVs all belonged to the same unit.)
7. Complete breakdown in command and control 1941.
8. Lack of reconnaissance, didn't become better until 1943.
9. Tanks lacking proper vision for commanders, fixed in T-34 with late model 1943 turrets.
10. Commanders acting as gunners on the most common tank.
11. Not having any hope of air superiority until summer of '43.
12. Poor operational art and poor tactics.
13. Mistakes, ooh all the mistakes. Mitigated quite a lot when they learnt how to fight. (3rd phase of the war in Soviet historiography.)
14. Difference in what counts as a lost tank. - (Cannot stress this enough. A German tank sent to factory for complete overhaul is repaired. A soviet tank sent to the factory for overhaul is lost and then produced again.)
15.All of the above. (ok maybe not #2.

)
Also Turtle I think he means this book:
The Red Army handbook It isn't a book by the Red army, but a study of the Red Army by Zaloga.
