Soviet Chemical, Biological weapons, in WWII?

Factual Questions

…Please pardon my posting, but I’ve been inspired by this thread to ask; did the Soviet Union have much in the way of Chemical, or even Biological weapons during World War II?

Thanks for your patience,

According to former Russian scientist Ken Alibek in his book “Biohazard”, the Soviets had weaponised Typhus,Tularemia and Q fever before and during WWII.

He claims that Tularemia was used against the Germans at Stalingrad: but see http://cns.miis.edu/research/cbw/tula.htm for a natural causes argument.

Also claims have been made that Q fever was used against the Germans in the Crimea in 1943.

But bear in mind that wartime conditions would allow the natural spread of disease.
