Q: I have a question regarding unit special rules that affect all
or some units within a certain range of a model or unit. How do
these interact with units inside Transports, and what happens
if the unit with the rule is inside a Transport?
A: When a unit embarks on a vehicle it is taken off the
battlefield and does not interact with anything on the
battlefield. However, certain rules may create exceptions
to this rule, with the most obvious examples being Fire
Points, psychic powers and Transports. If a unit’s rules
are meant to apply even when embarked on a Transport,
they will specify this.
Q: Do non-psychic powers with an area of effect (‘aura’ powers
like the Tau Ethereal’s Invocation of the Elements, or the effects
of many Warlord Traits) extend from the hull of a Transport
that the model with the power is embarked within?
A: No, non-psychic powers such as those described
cannot be used by models embarked upon a Transport
unless specifically noted otherwise.
