Assigned Agents If your army Faction is not AGENTS OF THE IMPERIUM, but every model in your army has the IMPERIUM keyword, you can include AGENTS OF THE IMPERIUM units in your army even if they do not have the Faction keyword you selected in the Select Army Faction step. In this case, the maximum number of AGENTS OF THE IMPERIUM units you can include in your army depends on the battle size, as shown below.
Incursion: 1 RETINUE, 1 CHARACTER, 1 REQUISITIONED
Strike Force: 2 RETINUE, 2 CHARACTER, 1 REQUISITIONED
Onslaught: 3 RETINUE, 3 CHARACTER, 2 REQUISITIONED
Note that you can include AGENTS OF THE IMPERIUM DEDICATED TRANSPORT units in such an army as normal, but each unit must start the battle with one or more units embarked within it, or it cannot be deployed for that battle and will count as having been destroyed during the first battle round.
Deadly Demise Some models have 'Deadly Demise x' listed in their abilities. When such a model is destroyed, roll one D6 before removing it from play (if such a model is a TRANSPORT, roll before any embarked models disembark). On a 6, each unit within 6" of that model suffers a number of mortal wounds denoted by 'x' (if this is a random number, roll separately for each unit within 6").
Firing Deck Some TRANSPORT models have ‘Firing Deck x’ listed in their abilities. Each time such a model is selected to shoot in the Shooting phase, you can select up to ‘x’ models embarked within it whose units have not already shot this phase. Then, for each of those embarked models, you can select one ranged weapon that embarked model is equipped with (excluding weapons with the [ONE SHOT] ability). Until that TRANSPORT model has resolved all of its attacks, it counts as being equipped with all of the weapons you selected in this way, in addition to its other weapons. Until the end of the phase, those selected models’ units are not eligible to shoot.
