If you purchase a Tiger, do so on the basis that it is going to be hit and killed/disabled quite quickly and not to your liking.
HE from under d2.0 is going to disable a track, town debris will result in go to jail, do not pass go, do not collect 200 etc.
I do suspect that some Tiger deaths, and panzer for that matter are purely random, and for that I feel your pain.
