Pistolier
From Warhammer - The Old World - Lexicanum
Pistoliers are the Empire light cavalry, fast, deadly and manoeuvrable. The short range of their pistols means that they will not fire many shots at their enemies before having to retreat. However, no armour can offer protection from the lead bullets, ensuring that every shot counts. While they are not suitable for prolonged engagements, they are excellent at disruption.
The survivors of this hit-and-run warfare usually join Knightly Orders. Some of them, however, cannot abandon the thrill and go on to become Outriders.
