From their website:
Tide of Iron fans rejoice. Fury of the Bear will unleash upon your tabletop the forces of the Soviet Union, as well as open the doors to a new theater of war. Things are heating up on the cold Eastern Front, and we would like to take this time to brief you on what to expect with Fury of the Bear.
This will be the first in a series of previews leading up to the release of Fury of the Bear. Today we’ll focus on the Red Army’s machines of war. To reflect the Soviet Union’s massive production of tanks during WWII, Fury of the Bear comes packed with the most armor of any previous Tide of Iron release.
