Ynnari and Vehicles

At first glance neither Strength From Death nor Power from Pain effects vehicles so if you're running a vehicle heavy all DE Ynnari list, it should not matter much if you run them as True Kin or Reborn, right? But then I reasoned that even if a significant amount of shooting is being done by my vehicles, as long as my infantry are nearby when things die the vehicles can better help my infantry take advantage of Strength From Death. Am I on to something?

Maybe.

Neither rule affects vehicle, you're correct. And vehicles dying does trigger SfD.

However, Haemonculi also affect vehicles (transports, anyway).
