Chosen

A unit containing Courageous must reroll failed Courage Tests.

A unit containing Fearless automatically passes Panic Tests, cannot choose Flee! as a Charge Reaction (unless it is already Shaken, or the entire unit has Feigned Flight).
In addition it ignores the effects of Horror.

The wearer's model gains Resistance (Toxic Attacks).

A model with Shield is considered to be using a Shield at all times, except during the Melee Phase if it is using a Two-Handed Melee Weapon.
A model using a Shield gains +1 Arm.
In addition, any Height 1-3 model using a Hand Weapon while using a Shield gains Parry.
Note: Shield provides no benefit against Melee Attacks when using a Two-Handed Melee Weapon .
Remember that since Shield (and parry) provide modifiers to Defensive Characteristics, their effects do not apply to a Character on a mount that has its own Defensive Skill or Armour.

A model part with Extra Support replaces the limit on the maximum number of attacks the model can do as Restricted Attack with the value in brackets (X) or, if it includes a +, increases that limit with +X.

During Combat Choices a model part can only choose a Hand Weapon if it has no other options, or is a Weapon Master.
Models with a Shield using a Hand Weapon gain Parry.
All model parts without Innate Weapons come equipped with a Hand Weapon as their default equipment and cannot lose it.
