Mobile defense scenario

[Turner]

Looking for a scenario which has a mobile defensive setup. Infantry division(s) forming the main line of defense which is pressed into a retreating, delaying action and a mobile panzer reserve to be used when and where the player want to.

A scenario that give the player a lot of options how to use the panzer units. Reinforce the line or allow the enemy through only to cut him off and isolate him?

There's got to be scenarios like that, it's just that there are so many I've not looked through all of them. Any recommendations from veteran players? I have all east front titles but Budapest '45.
