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.
Deep Strike During the Declare Battle Formations step, if every model in a unit has this ability, you can set it up in Reserves instead of setting it up on the battlefield. If you do, in the Reinforcements step of one of your Movement phases you can set up this unit anywhere on the battlefield that is more than 9" horizontally away from all enemy models.
If a unit with the Deep Strike ability arrives from Strategic Reserves, the controlling player can choose for that unit to be set up either using the rules for Strategic Reserves or using the Deep Strike ability.
