Primus Redoubt

If a model has a Transport Capacity and the Garrison Vault special rule, then it may transport any number of Infantry units (plus any Characters that have joined the units), so long as the number of models in the Embarked units do not exceed the model's Transport Capacity. Some models when the Garrison Vault special rule may be able to transport other units in additiona to Infantry. Where this is true, the model's profile will note exactly which units may Embark on this building.

Battlements are treated as an Access Point for their Building, meaning a unit inside the building can disembark onto the Battlements, or vice versa. Note that buildings without Transport Capacity that have battlements may still not be entered, although units can use their battlements.
Units equipped with Jump Packs of Jet Packs, Vavalry units and Skimmers do not need to take Dangerous Terrain tests for starting or ending their move on battlements.
If a Template or Blast weapon hits a unit on top of a battlement, that battlement's Building also suffers a single Hit.
If a unit moves onto the battlements of an Unclaimed, non-destroyed Building, they immediately Claim that Building and it becomes part of the unit's side until the Building is either destroyed or an enemy unit Claims it.

• A model with the Building Sub-type has an Armour Value instead of Toughness Characteristic and a reduced profile to reflect its limited capabilities. Page 224 of Warhammer: The Horus Heresy – Age of Darkness Rulebook presents rules for making attacks with or against models with this Unit Sub- type.
• A model with the Building Sub-type uses all of the rules for the Transport Sub-type and other models with either the Infantry or Primarch Unit Types may Embark or Disembark upon them (see page 224 of Warhammer: The Horus Heresy – Age of Darkness Rulebook).
• A model with this Unit Sub-type may never Move or be Moved by any special rule or effect – if it is forced to Move then it instead suffers the effects of the Total Collapse result on the Building Damage table.

No model with any versions of the Bulky special rule may Embark on a model that has this special rule.

Massive Fortifications follow all the rules for Buildings as defined in this section, and reduce all rolls made for them on the Building Damage table by -1. The profile entry for the Fortificatoin will list the actual Armour Values it has.
