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.
Leader While a Bodyguard unit contains a Leader, it is known as an Attached unit and, with the exception of rules that are triggered when units are destroyed (pg 12), it is treated as a single unit for all rules purposes. Each time an attack targets an Attached unit, until the attacking unit has resolved all of its attacks, you must use the Toughness characteristic of the Bodyguard models in that unit, even if a Leader in that unit has a different Toughness characteristic. Each time an attack successfully wounds an Attached unit, that attack cannot be allocated to a Character model in that unit, even if that Character model has lost one or more wounds or has already had attacks allocated to it this phase. As soon as the last Bodyguard model in an Attached unit has been destroyed, any attacks made against that unit that have yet to be allocated can then be allocated to Character models in that unit.
Each time the last model in a Bodyguard unit is destroyed, each CHARACTER unit that is part of that Attached unit becomes a separate unit, with its original Starting Strength. If this happens as the result of an attack, they become separate units after the attacking unit has resolved all of its attacks.
Each time the last model in a CHARACTER unit that is attached to a Bodyguard unit is destroyed and there is not another CHARACTER unit attached, that Attached unit’s Bodyguard unit becomes a separate unit, with its original Starting Strength. If this happens as the result of an attack, they become separate units after the attacking unit has resolved all of its attacks.
Each time a unit that is part of an Attached unit is destroyed, it does not have the keywords of any other units that make up that Attached unit (unless it has those keywords on its own datasheet) for the purposes of any rules that would be triggered when that unit is destroyed.
