Yes. See the Warhammer Annual 2002. View online.

Yes. Writing down previous guesses pretty much reflects how a "real" artillery captain would work.

An abandoned war machine has no effect on movement.

Yes.

Yes. Note that if a war machine is already abandoned when charged, it is destroyed, but no combat results are worked out, no Panic tests required, no overrun can be made, etc.

No.

No. War machine crews are not allowed to declare charges. Further, it has been clarified that a war machine crew may never leave their war machine except to crew another war machine which has no crew left or if they flee.

No. They are required to flee.

No. A war machine crew may never leave their war machine except to crew another war machine which has no crew left or if they flee.

No. Per the Q&A recently issued in Warhammer Chronicles 2004, war machine crews are no longer allowed to pursue enemies who break and flee from close combat.

Yes. Per the Errata in Warhammer Chronicles on Attacking a Machine - Replace both paragraphs with: A war machine cannot be attacked in close combat while it still has crew. A war machine that has had its crew wiped out or broken in close combat is assumed to be spiked or otherwise disabled by the attackers, on the condition that they do not pursue or overrun. If a war machine is already abandoned when charged, it is destroyed, but no combat results are worked out, no Panic tests are required, no overrun can be made, etc.

Yes.

No. When the crew is not attached to the machine, a war machine is considered to be a single model and if it has less than 5 wounds on its original profile then its destruction by the enemy will not cause a panic test.

No. If a war machine is already abandoned when charged, it is destroyed, but no combat results are worked out, no Panic tests are required, no overrun can be made, etc.

No test required. The panic test for friends destroyed is very specific about enemy magic and shooting again. In this case, most soldiers are just waiting for the whirly-gun of doom to blow itself up. They're pretty used to this type of behaviour.

Yes. No exceptions for war machine crews in regards to these types of panic tests are given in the Rulebook. Remember that if a separated war machine's crew has been reduced to only a single model to apply the panic test exemptions given for single models with less than 5 wounds on their profile.

No.

Yes. While crew losses from enemy shooting or magic does not force the war machine unit to take a panic test, no such exemption exists for loss of the machine.

No. A war machine may not be fired until the turn after it has been re-crewed.

This takes effect after the next time it is fired. In other words, the war machine can fire again one more time before having to take extra time to reload.

No, Victory points are only scored for destroying it (or the equivalent, as detailed in the War Machines section of the rules).

No. A cannon ball is treated as a thin template at thus hits whatever falls under the line it passes through. The section on randomizing hits on warmachine units applies to fire from missile weapons and magic missiles and does not apply to templates. In addition, remember a war machine is not a model with multiple parts, it is a unit with multiple models.
