Red Army = most effective force !

"If you reread my post you'll see I said digging deep trenches (easily done even with commercial diggers) to block trucks driving around blocked roads not in order to block the roads. So that'd be next to roads and in fields, not the roads themselves. Also a good and very quick way to make those exit points a lot harder to make work."

Which requires digging hundreds of meters or kilometers of deep trenches.With the commonly available commercial equipment that is a very time consuming affair, not something that can be done on the fly. The only way such task can be carried out in a reasonable timeframe is with chain escavators, like the soviet PZM series. From what I have seen this isn't the sort of equipment that your typical local construction firm will generally have in the inventory.

"On the whole your argument seems to be that it would be hard for NATO to demolish things effectively while it would be fairly easy for the WP forces to overcome them. I think you've got it the wrong way around. It is much, much easier to demolish and block than it is to clear and circumvent."

But in reality many of the actions you are describing are actually construction activities. You are calling for building obstacles requiring extensive digging and earth moving. Such activities are actually very time consuming and as they would require damaging infrastructure, infringing private property etc. it would be unlikely that they would be carried out until the war was a sure thing.By then it would be too late to carry them out in an extensive manner.

"Well so did NATO, the germans in particular"

I have no doubt that they were prepared to blow up bridges,laying minefields (much faster than trench digging) and such. What I have a lot of reservations about is much of the rest, like blowing up off ramps and so on.If they were in the plans and the necessary preparations (pits for the demolition charges etc.) had been made, by any means tell me so. If they are just ideas being tossed around, then they are not very practical.
