I'm not crazy about "Immobilization!"

This represents the possibility that a vehicle will break or bog down. I believe that formula in the rules is actually incorrect. I believe that it is the cost of the hex divided by the immobility constant and then modified by the vehicle's reliability factor. I asked Rich if this was correct during Falklands, but never got an answer. For a normal, dry condition scenario, this would equate to about a one in a thousand chance (0.1%) to breakdown for each open hex entered for an A rated vehicle (movement cost of 6 divided by constant of 6000 modified by reliability of 0.97 to 1.00). Different ground conditions cause the movement factor to increase also causing the chance for a breakdown to increase. In addition, the scenario designer can change the constant value in the pdt to simulate poor conditions (I believe it is 4000 in Falklands to simulate the boggy ground there as well as high movement costs for wheeled vehicles).

Other Tiller games such as Panzer Campaigns, include this type of loss. The Panthers assigned to GrossDeutschland during Kursk are a good example of why this type of rule is included. The engineering bugs had not been worked out of the powertrain when they were sent into action and as many as 90% of those not disabled by mines broke down.

Hope this helps you understand the risk and the reason for this rule.
