The German tendency to assume that any new Soviet reinforcements in 1941 came from Siberia is well known, but turns out that along with mythical Siberian riflemen there were mythical Siberian tanks as well:
"16th Infantry Division (motorized)
Department 1 (intelligence)
"16th Infantry Division (motorized)
Department 1 (intelligence)
Division HQ
October 7th, 1942
Intelligence agents report that new heavy tanks from Habarovsk have been sent to the European front. Tanks made in Habarovsk are allegedly labelled with the letter H and also "Habarovsk, Osoaviahim".
Immediately report the arrival of these tanks to the intelligence department of the division."
