Shield

A model that carries a shield improves its armour value by 1. For example, a model equipped with light armour has an armour value of 6+. Should that model also carry a shield, its armour value would be improved by 1 by lowering the target number from 6+ to 5+.

Note that if a model uses a weapon that has the Requires Two Hands special rule in combat, it cannot also use a shield.
