Detachment Rule

Surprise Assault

Burrowing Tyranid bioforms burst from the ground in all their horror.

Each time a Tyranids model from your army makes an attack, re-roll a Hit roll of 1.

Each time a Burrower unit from your army is set up on the battlefield from Reserves, place a circular 40mm Tunnel Marker anywhere on the battlefield within 1" of that unit and more than 3" horizontally away from all enemy units.

In the Reinforcements step of your Movement phase, when you set up a unit on the battlefield from Reserves, you can set that unit up wholly within 9" of one of your Tunnel Markers and more than 6" horizontally away from any enemy units.

If an enemy model (excluding AIRCRAFT) ends any kind of move within 3" of one of your Tunnel Markers, that Tunnel Marker is removed from the battlefield.

KEYWORDS
Mawloc and Trygon units from your army have the BURROWER keyword.

In the Muster Armies step, you can select up to 2 TRYGON models from your army. The selected units gain the CHARACTER keyword.

Designer’s Note: This means that the selected models can be given Enhancements and one of them can be selected as your WARLORD.
