You can include UNALIGNEDFORCES units in your army even if they do not have the Faction keyword you selected in the Select Army Faction step. The combined points value of UNALIGNEDFORCES units you can include in your army depends on the battle size, as follows:
Incursion: Up to 250 pts
Strike Force: Up to 500 pts
Onslaught: Up to 1000 pts
No UNALIGNEDFORCES models can be your WARLORD.
6. Select Warlord
Select one CHARACTER model from your army to be your Warlord – this will be the leader of your army – and make a note of this on your Army Roster. Your Warlord gains the WARLORD keyword.
