Glad this is cleared up:

Q: In the rules for cover saves it says that intervening models grant cover even if the model is fully
visible unless you shoot over the intervening models. Does this include models that are taller than
the intervening models i.e. are taller models able to shoot over shorter models?
A: Yes, as long as the line of sight for the weapon being used is not obscured by the
interveningmodels and does not pass through a gap between the models in the intervening unit
