Although they're nasty and somewhat indiscriminate, they have been used in the past and the Soviets were well prepared to use them again. My research has revealed that they had developed defences in parallel to their offensive capability - not perfect by any means, but it put them in a MUCH better position than the west.
Like any weapon there's a time and a place for them (hopefully nowhere and never, but should we really shove our heads in the sand over the possibility?) Certain regions lend themselves to the use of biologicals more than chemicals or nukes, and other regions make their use near suicidal (transportation links, population density, etc all factor into it).
So, getting back to my original question, has anyone stated them out, even in just a rudimentary way?
Here's a couple of videos on the subject and a link to a page I've found interesting and informative.

Also worth a read is this book "Plague Wars: the Terrifying Reality of Biological Warfare".
