Is immobilization excessive?

[Dog829]

Right now playing a scenario Crisis on the Mius I have lost 8 tanks to immobilization and none of them due to enemy fire come on I can see maybe one or two but 8 its ridiculous.These are T-34's they ran better than any Panzer as for going cross country there tracks were wider they were designed for being driven on open terrain

Is this an odd coincidence? This IS the exact scenario that started me asking the question to myself. Then I said something to CK2 who I am still playing this scenario against in pbem. I'm the Russian player in this one and the number seems close to what I experienced. I think mine was a little higher. I'd give you a number but many have since been destroyed. I still have four or five left in the field.
But then later I was playing Vorskla Valley as German vs A/I and lost three tracked vehicles while moving on trails within the first 5 turns that prompted it. No combat, nothing. Final count was eight vehicles. One was a truck, the rest tracked.

Big Red One commented earlier that he didn't have any knowledge about the mechanical reliability of WW2 vehicles. I don't either, I doubt such data exists.
What I do know is I have played RV quite a number of times. Some pbem, most vs A/I and this seems really excessive to me when compared to my overall experience with this game.
