Aceeptable Losses

ASTRA MILITARUM (Not in Engagement
Range) can target enemy unit even if it is
within Engagement Range of other friendly
PLATOON/GRIM DEMEANOUR units,
but each time a model makes an attack
against such a target, that attack’s hit roll
cannot be re-rolled and on an unmodified
hit roll of 1, resolve that attack against one
friendly unit, selected by you, that is within
Engagement Range of the target instead.
