Yeah, Kampfgruppe Engel and Tiger Poaching in particular really are fantastic.
As much as I enjoy the straightforward attack/defend missions, breaking them up with the odd fluid battle like this one is great. You have to make some tough decisions as to which forces to push to the tiger with (and how fast) and tactical withdrawl missions are always real nailbiters - you have to inflict as many casualties as possible, but leaving units in place for even a few seconds too long can lead to their destruction. Great fun.
I managed to do pretty well on this mission, but I was super lucky. I pushed hard for the tiger with both PzIVs, a Panther and a support halftrack backing up a platoon of inf and what was left of my pioneers. I withdrew them under a smokescreen, but it cleared up sooner than I anticipated and my Panther found itself less than 50m away from a full platoon of Shermans, all of which it managed to KO suffering only a damaged track and radio. I parked the same Panther further back where it KOd a few more tanks before getting knocked out right at the end - it must have taken at least a dozen direct hits, but they kept pinging off the armour, giving me enough time to get lots of men to the exit zone.
Like I said, a reeeeal nailbiter.
