Cavalry's Ride-By Attack

Ride-by Attack
A cavalry model can combine its normal movement and
action in a ride-by attack. Declare that the model is doing so
at the beginning of its normal movement. The model makes a
full advance and can halt its movement at any point to make
its combat action. Do not resolve abilities that trigger when
the model ends its normal movement at this time. After it
ends its combat action, the model resumes its movement.
Therefore, a model making a ride-by attack triggers endof-
action effects before end-of-normal-movement effects. A
cavalry trooper making a ride-by attack must complete both
its movement and its combat action before the next model
begins its normal movement.
Models in a cavalry unit must receive an order to make
a ride-by attack. A cavalry model that received a ride-by
attack order can make its attacks that activation even while
out of formation.
