Independent characters follow the Movement rules for models of their type, be it infantry, jump infantry, bike, etc. In addition, independent characters can move through difficult terrain more quickly and safely than ordinary troops. All independent characters have the ‘move through cover’ and ‘skilled rider’ special rules. This advantage does not extend to any vehicles they may be travelling in.

Independent characters are allowed to join other units. They cannot, however, join vehicle squadrons (see the Vehicles section) and units that always consist of a single model (like most vehicles and monstrous creatures). They can join other independent characters though, to form a powerful multi-character unit!

A Rosarius confers a 4+ invulnerable save.

Models equipped with assault grenades don’t suffer the penalty to their Initiative for assaulting enemies through cover, but fight as normal.

When assaulting a vehicle, each model using Krak grenades can only ever make one attack, regardless of the number of Attacks on their profile and any bonus attacks. Against vehicles, Krak grenades have an armor penetration value of 6+D6.
