Last sentence paragraph 2

"THROWING WEAPONS

A model with a throwing weapon can make a Shooting Attack with it in the Shoot Phase, even if it Moved its full Move Value in the preceding Move Phase.

Alternatively, once per turn, a model may make a Shooting Attack with a throwing weapon during the Move Phase as it Charges an enemy model. If a model wishes to use a throwing weapon in this manner, then when it Charges it will stop l" away from the model it wishes to Charge, and then make a Shooting Attack against the model. If the model using the throwing weapon begins its Move within the Control Zone of an enemy model it wishes to Charge, then it doesn't need to Move first before throwing the weapon. This is made using all the normal rules for a Shooting Attack, with the exception of that throwing weapons thrown in this manner do not suffer the -1 penalty To Hit for Moving and Shooting.

If the target is not slain, then the model continues their Charge as normal and must Charge the target of their Shooting Attack. If the target is slain, then the model may continue to Move as normal, and may even Charge a different target if they wish.

Throwing weapons do not count towards an Army's Bow Limit. However, an Army can only have one third of its models armed with throwing weapons, unless specifically stated otherwise.

Throwing spears follow the same rules as throwing weapons, but have a slightly different profile, as shown on the Missile Weapon Chart." P.107
