1. Page 118 If a character joins a War Machine, and has a missile weapon, could he Stand & Shoot that weapon? Or since he is part of the Crew unit, and that unit cannot S&S, therefore he cannot as well?

Unless specifically acting as crew (i.e. an Engineer who used his ability the previous turn) a character who joins a unit is not considered crew and so may stand and shoot. 

1. Page 58, then pages 93 & 94, Throwing Axe has two different ranges listed. I assume 6" is correct (from pages 93 & 94) rather than 4" from page 58.

Yes, 6" is correct.

 1. When Overrunning. Page 78 Second column Para 2 "May be necessary to wheel slightly" My question is basically 'How much is slightly?' Are there any guidelines (i.e. wheeling to engage the most models and possibly avoid 'clipping' is okay, Wheeling to grant you a new target is not.

The target unit is determined by the direction of your overrun move - i.e. the one straight ahead. After this has been determined, the player must get as many models into contact with the enemy as possible, as per a normal charge. This does not allow you to ignore the first unit you would normally hit and go for another one.

2. When addressing striking first in combat Page 68. If the I value is equal between the two models and the roll off is also a tie do you actually strike simultaneously or roll again till you don't. The rules don't indicate either way.

Roll off until you have a winner.

 3. Subsequent fleeing.... Page 75 First Column. Fleeing troops move toward a table edge "it will move round obstacles including units of troops..... will not move within 4" of an enemy unless they have no choice. If they are surrounded for example."

Does this question make sense?

They must make all attempts to flee off the battlefield. After this primary concern, they will, if possible avoid enemy units, unless this means they are not fleeing the battlefield as quickly as possible. I.e if they can't go around a unit without getting within 4" then they will approach closer, otherwise they'll circle around along the shortest available route.

 4. On page 54 of the Warhammer Rulebook, left column, at the bottom, you'll find the following phrase - "Individual models (the assumption being individual models that are part of a unit of many, as opposed to single models like a character) can turn to face the chargers and avoid this test _and any other penalties_, unless they are already engaged in close combat."

Is this correct?

Units that consist of a single model are individuals, obviously, but Skirmishers also function the same way. Normal ranked units can't be worked this way as if they did the whole point of flank charges wouldn't work.

 Psychology

 1. On the Fear test (page 81) - what if your Unit Strength is _equal_ to the enemy when you fail the test? Flee or 6's to hit?

You should change 'Higher' to 'equal to or Higher' in the section on being charged by a fear-causing enemy (this is going into the reprint editions)

2. Page 80 Under item #2: If a unit has only one model left in the unit the turn it is destroyed in combat, does unit nearby have to make a panic test? (i.e. does the last model in the unit count as a single model, or still as a unit?)

This is determined at the time it was destroyed (i.e one survivor wont make you test, two survivors will)

3. Page 80, item #3, Panic Checks for Side/Read Charges: It says that you use the Unit Strength (5 or more) to require the check, but then says at the end that no test is required if the charging unit is less than 5 models. Is that last sentence a typo, and should not be there, or do you only do a test if you have both 5 or more models_and_Unit Strength of 5 or more?

Just mentally delete the last sentence. A Unit Strength of 5 is the only requirement needed.

 Weapons

1. If a character is carrying a magical weapon and a shield, on foot, do they get the +1 AS bonus? Mention is made that magical weapons don't get the 'special rules' from their mundane counterparts. I didn't know if this was an oversight or if the intent was for magical weapons to not get the +1 AS bonus. Now the funny bit. If a character is carrying a hand weapon and a magic shield, on foot, do they get the +1 AS bonus?

No bonus in either case. As you point out, the presence of a magical weapon or a magical shield will negate the special rules for mundane items. As both hand weapon and shield are required for the mundane rule of +1 armour save, having a magical one of either cancels that special rule.

 1. Page 95 Characters Marching: Do these rules only apply to foot characters or are mounted characters included?

The section on character movement is a little contradictory. To make things clearer, we've decided that all of the special character movement rules apply only to characters on foot - the marching rules, 360° arc of sight, etc. Characters on mounts or monstrous characters (i.e. those with 6 or more starting wounds) follow all of the normal movement rules regarding arc of sight, marching, terrain etc. Note that like chariots and monsters, such characters do not need to wheel or turn as such, and can move freely in any direction.

They still have it (and are still a 2 model unit). If they decide to split up then you can choose which of them retains the captured standard.

 Special Rules

1. Page 113 Regeneration: Can a model slain by another model with Killing Blow, that rolls a 6 on the to-wound roll, Regenerate?

You cannot regenerate a killing blow, and note that for combat resolution purposes use the remaining wounds of a model slain by killing blow.

 Fast Cavalry

As is normally the case, the main rules are correct.

 1. I noticed that templates for spells and templates for war machines worked in two different ways, is there a reason for this. See Pg 121 and139 (Just wanted to ensure they are indeed different)

Refer to the individual spell descriptions.

 Magic

1. Comet of Casandora is a Remains in Play, but doesn't have the standard "stays in play until Wizards wants to cancel it, or he dies" bit like other RiP spells. Should it have these words, or is it so powerful that it must be actively dispelled to stop it, and survives even if the caster dies?

Once the comet is on its way, that's your lot - you can jump and down on the wizard all you like, it ain't gonna stop fifty tons of star iron slapping into the battlefield.

2. For the Bane of Forged Steel it says that unit would now be considered to be using hand weapons, does this improve the save of the unit if they have shields and what is the affect if any on a unit already with hand weapons. ( the +1 armor save for hand weapon shield isn't listed with the weapon bonuses.)

They have a hand weapom so all of the rules that apply to hand weapons count.

3. Page 75. Rallying at start of the turn: If you do so, could you move the unit via Magic and then fight in close combat? It says you cannot Shoot or Fight, and cannot do any other Movement in the Movement Phase, but via Magic you could relocate the unit into contact with the enemy. If so, would they actually fight in the Close Combat?

They would fight as any other unit.

1. Page 154 Dispel Scroll: Should the last paragraph, second sentence read, "Any spell that is successfully cast with a result of double sixes is irresistible and no Dispel roll is permitted." Instead of ".... result of 12 is irresistible..." (You could easily get a result of 12 without rolling a singe 6)

Yes, it should be double sixes

 2. The rules for magic Items state that a character with a magic item cannot use other close combat weapons (pg 152). What is the affect of the Law of Gold , once a magic weapon cannot be used? Can the Character attack at all, and if so how?

Characters generally come with a hand weapon, so they'll have to use that instead,

3. Have a general and a specific question. The general question is "Does Magic still 'Trump' normal rules where they contradict?" Which leads to the specific question "Can a unit of Knights led by the a Templar Grand Master (making the unit Immune to Psychology) carry and get the benefit of having the Banner of Sigismund (making them Stubborn)?"

There is no magic vs mundane trump anymore. In the example you give, the banner would have no effect - immune to psychology is immune to psychology.  If it were otherwise, you’d get situations where a player could say 'My Dread banner is a magical fear and so therefore overrules your mundane immunity' which of course is not the case.

 4. Can You use a Dispel Scroll to dispel a spell that was cast in a previous turn and has remained in play?

No. It says in the description of the item that it needs to be used "as soon as a spell has been cast". Obviously if the spell was cast in the previous turn this won't be the case.

They can

 2. We noticed that in a battle of less than 2000 points a Demon host army cannot have a General.... Can you play without a General? The rules don't specifically say that you can not (that we could find). Seems kind of odd to us though. If you cannot, can you play with a Demon Host army of less than 2000 points?

Yes, I spotted this too. I think it would be okay to use an Exalted Daemon as your general in battles under 2,000 points (2,000 points or more you still need a greater daemon).

3. 'Do you have an errata or a clearer working of the lance formation and how it works. As it stands, the current explanation in RH is very confusing. Some people think that you must spend a turn reforming after combat. i.e. If you win combat on turn 2, you spend turn 3 reforming into a lance, and move on turn 4.

If your lance doesn’t break through intact on turn 1 it'll dissolve into a mass. As the Bretonnians are trained to fight in lances and not otherwise, as soon as this mass becomes unengaged it must spend a turn reforming. This is one of the disadvantages.

 4. Lizardmen: Hero’s Cold One is listed as having 1A. Is this correct?

Lizard Hero Cold Ones should be amended to 2A like al the other entries for CO. DE list is OK  

5. In the list for Beastmen the trolls aren't stupid. Correct or not?
