It now has a lot more detailed rules for creating a retinue for your inquisitor, with each member having a lot more detailed rules / impact.
There are limits based on which Ordo you are on what you can take in your retinue.
The whole book is just for creating 1 HQ choice, which can be taken by any Imperial army, including as the mandatory HQ.
i.e. you could have a space marine army without a captain/librarian/chaplain/master, lead only by an Inquisitor.
No troops, no elites, no fast attack, no heavy support.
