вот ответ на твой вопрос:

Q: Can a model use a psychic power that is not a
Psychic Shooting Attack if it is embarked in a transport
vehicle? (p50)
A: Yes. If the power requires line of sight, this is still
worked out from the vehicle’s fire points (this will
count as one model shooting through that fire point if
the power is used in the Shooting phase).
If the psychic power does not require line of sight and
has a range or an area of effect that is normally
measured from the model using it, these are measured
from the vehicle’s hull, as explained in the Embarking
section on page 66.
