Shaken troops

Shaken troops cannot move, shoot or change formation. They can still fight HTH if charged.
Excepting Skirmishers, a shaken unit must pass a formation test to retire (i.e. Move straight back facing the same direction and in the same formation) up to half their normal move distance.
If joined by their General figure they can, without testing, retire or make a formation change, and also shoot. They will be rallied if he remains with them for one complete turn and they are not involved in HTH combat for that time.
A shaken unit involved in a combat where an enemy unit is routed is automatically rallied.

Examples of shaken troops in different formations. The elements are placed at a small angle to each other, or in the case of a square one element is turned inward.
