Reiksguard

Reiksguard is a Empire cavalry unit in Total War: Warhammer. Equipped with the best armour and weapons, Reiksguard deliver a powerful charge, then remain amongst the throng to continue fighting.

Description
The Reiksguard Knights are the personal army of the Emperor. As an Elector Count, the Emperor also has direct command of his own provincial army - which in the case of Karl Franz are the regiments of Altdorf and the Reikland - but it is the Knights of the Reiksguard that form the symbol of his military strength. As befits their prestigious role and elite status, the Knights are equipped with the very finest weapons and suits of armour available. They ride fine destriers to war and the suits of gleaming plate armour in which they are clad are emblazoned with symbols of allegiance to the Emperor. Although few in number, the Reiksguard Knights are the most important part of the Emperor's army, for they are a symbol of the Empire's nobility and martial might. As such, when a unit of Reiksguard Knights takes to battle, it will typically form up proudly in the centre of the Empire battle line, the better to inspire the common soldiery and reassure them that the blessing of the Emperor is with them.

Strategy
Reiksguard have a notably high charge bonus. This gives them a large, offensive buff after a successful charge that deteriorates linearly over 15 seconds. Abuse this by charging a unit and pulling the Reiksgaurd out 8-10 seconds after the charge connects, then charge again to refresh the bonus.

Despite the Reiksgaurd's impressive armor stat, their poor melee defense causes them to receive consistent damage when engaged in prolonged combat. Avoid charging head on into high quality units, even if they lack armor piercing.

A popular strategy is to focus all of your Reiksgaurd on a particular side of the battlefield in order to 'win' that side, freeing up your infantry to collapse on engaged troops down the frontline.

* Another authors note: A particularly prevalent misconception among newer players is that these are "Elite" cavalry. They are very good still, probably at the highest end of the middle tier, but do not think they will continue to carry your battles like they do in the early game.

Do not think this is denigrating them. Reiksguard are still good cavalry and vital units to the empire roster. Just knowing their role in a combined arms force instead of as the backbone of your game plan is instrumental to the growth of an Empire general.
