I know that during artillery fire, a battery may not pivot if it would change the firing range . It has to fire at the eligible targets and during moveent phase try to move to change angles and have anther target, juicier and at a shorter range .
But I cannot remember if you may pivot during the firing phase in order to avoid having to fire at 2 different units at same range and so concentrate on one target . Same idea for not shooting at one target but having a new target you prefer ( always same range ) .
