Boarding Swarm

Do not split ^^**Hormagaunts**^^ into separate units in the Form Boarding Squads step.

You can include up to two of the following units (duplicates are not allowed):
- **^^Deathleaper^^**
- **^^Lictor^^**
- **^^Neurolictor^^**

You can include up to two of each of the following units:
- **^^Hormagaunts^^** (10 models)
- **^^Raveners^^** (3 models)
- **^^Von Ryan's Leaders^^** (3 models)

- **^^Hormagaunts^^** units cannot perform the Secure Site Tactical Manoeuvre.
- The **^^Lictor^^** model loses the Pheromone Trail ability.
- The **^^Raveners^^** unit loses the Death From Below ability.
- The **^^Von Ryan's Leapers^^** unit loses the Pouncing Leap ability.

Each time an enemy unit within Engagement Range of one or more **^^Tyranids^^** units from your army is select to Fall Back, after that enemy unit has made that Fall Back move, for each of those **^^Tyranids^^** units, if there are no other enemy units within Engagement Range of it, it can make a Normal move of up to 3".

Units from your army with the Shadow in the Warp ability retain that ability.

Units from your army with the Synapse ability retain that ability and gain this one.

When measuring whether a unit from your army is within Synapse Range of a friendly **^^Synapse^^** model, Walls and closed Hatchways are ignored.
