Subterranean Assault
(Rule)Description: If, when a Trygon (or Trygon Prime) deploys via Deep Strike, it scatters on top of
impassable terrain or another model (friend or foe), reduce the scatter distance by the
minimum required to avoid the obstacle.
After the Trygon (or Trygon Prime) has emerged, mark the position under the creature's
base with a suitable marker - this represents the tunnel left by its emergence. Any
friendly Tyranid Infantry unit that arrives from reserve in subsequent turns may emerge
from the Trygon's tunnel instead of arriving from reserve as normal. Only one unit may
emerge from each tunnel marker each turn.
If any unit chooses to do so, place the entire unit so that all of its models are wholly
within 6" of the centre of the marker and in unit coherency. These models cannot be
placed within 1" of enemy models or within impassable terrain; if any models cannot be
placed, these excess models are removed as casualties. A unit may not move or charge on
the same turn it arrives from a Trygon's tunnel, but may shoot or Run.
