Charged units performing the Hold and Shoot Charge reaction (thus called Holding and Shooting units) Turn to Face the Charging unit and immediately perform a Shoot action (with the Charging unit being the only potential Target unit) immediately before they receive the Charge.
As written, it appears the Shoot Distance used by the Holding and Shooting unit will be the same as the Charge Distance of the Charging unit.
What about cases where the Shoot Distance is beyond the Maximum Range of the weapon (Dyndraig breath, for example), or the weapon has a lethal range? Is it possible for the Holding and Shooting unit to wait for a better time to shoot?
