Mud Movement penalties seem low

[Bacillus98]

In my opinion, realism in a wargame should translate to how well does the game implement the aspects of war that is supposed to model. To its credit, the current incarnations of the Panzer Campaigns series seem do most of this quite well according to the veterans of the game. Also, there is an inherent advantage in using computers to help with the simulation. However, in its current state, the stock PzC Moscow 41 campaign has German armor/motorized units moving too fast in heavy mud, especially motorized units. Based on some information I analyzed, it states that despite muddy conditions, the Wehrmacht was able to move, albeit much slower than the summer offensives. I plan to speak with a local military history professor soon to hopefully obtain more info in regards to the campaign. A few historical examples of mud movement include three German corps that managed to move 70-80 km in 5 days. 1st Panzer Division was able to move 75 km in 5 days. All of this indicates tactical movement slower than stock speeds. Wheeled vehicles had an extremely difficult time on or off road. Between Oct. 24-Nov. 13th, there was an operational pause between both sides. AGC was only able to conduct limited offensives during this period. The Russians were scrambling reserves to form some semblance of a defensive line in front of Moscow. I apologize if my view on realism is a thorn in the side of playability. I naturally assumed since the computer can do all the number crunching, a representation of fairly realistic movement in adverse conditions isn't something that should be avoided. Slow movement in the mud is akin to the slogging attritional battles like Kursk or wide open encirclement maneuvers like Smolensk, different flavors for different folks. I do also realize this is something that isn't a one step solution as Glenn has mentioned. All I ask is that it should be considered to a stronger degree that it is now. I'd love to help anyone by giving them info on applicable campaigns in regards to combat operations/movement in inclement weather.
In summary, the view of many historians have indicated that Russian weather (including Rasputitsa) and German High Command strategic mistakes saved the Russians in 1941. I want to end the post with a few pictures of "General Mud" to get a sense of what those virtual counters are encountering :)
