No. I think that if you allow this to happen, you make a mockery of one of the most important dynamics of Warhammer strategy - moving your troops into a position to get the most advantageous charge. This may seem a bit odd, particularly with skirmishers as in this example, but the rules clearly state that to charge in the flank/ rear, the majority of the charging unit must be in that zone, and there are no exceptions. To get a flank or rear charge, you should have to positively move the unit into a position where it can do this, rather than simply fill up the front with other stuff.

Co-ordinating units to get simultaneous front and flank charges is a defining tactic of Warhammer and should be something that is tricky to achieve, otherwise the game will lose any sense of the importance of planning and maneuver.

No. You can only redirect a charge against a unit if you could not have declared a charge against them normally, but can now do so due to the enemy fleeing.

No. First, remember that you do not declare whether or not you will be redirecting a charge until after the fleeing unit has completed its movement. At that point, you must make a decision on whether or not you wish to chase the fleeing unit or redirect into the newly revealed enemy unit. It is critical to follow this order as in some cases the fleeing unit may not flee very far, and actually prevent the second enemy unit from being revealed as a target.

To determine if a unit can perform a stand and shoot reaction, you must calculate the actual charge movement expended (taking into account wheels, difficult terrain, etc.) by the charging unit(s). If one or more charging units can expend half or less of its charge movement to complete the charge, then the defending unit may not stand and shoot.

Yes, as long as the failed charge brings the charging unit into range
of the defender's missile weapons.

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

In cases where the stand and shoot is resolved before the charger moves, the rider will be on foot before the model starting moving. In this situation, the rider should attempt to complete the charge using his own charge move.

In cases where the stand and shoot is resolved after the charger has started moving (which only happens if the charger starts out of range of the defending unit's missile weapons) the charge fails automatically at the point the monstrous mount was killed.

In cases where the stand and shoot is resolved before the charger moves, the character will be on foot before the model starting moving. In this situation, the character is allowed to be placed anywhere within 2" of the destroyed chariot and he should attempt to complete the charge using his own charge move.

In cases where the stand and shoot is resolved after the charger has started moving (which only happens if the charger starts out of range of the defending unit's missile weapons) the charge fails automatically and the character is placed anywhere within 2" of the destroyed chariot.

If the character is the only one left, the unit has been destroyed and therefore the character is no longer a part of it. Since the character is above 25% of their own starting size they will always be able to rally.

Yes. As units that utilize random compulsory movement do not declare charges, they are not restricted from coming into contact with an enemy unit on the turn they return to the table.

In Appendix Six (Rules Commentary) of the Warhammer Rulebook. View online.

Yes, the rule about splitting the frontage of the target unit still applies. The Appendix Six (Rules Commentary) guidance does not provide an exception for single models. The maximize chargers rule found on page 52 of the Rulebook is still applied, however it is simply applied to the portion of the target unit each charging unit has been allocated. Note that resolving the alignment of the combatants in this manner has the important benefit of reducing clipping situations.

The rules do not allow us to come into contact with an enemy unit during the Move Charges step of the movement phase unless A) valid charge or re-directed charge was declared against the enemy unit we wish to contact or B) the unit was "drawn-in" to the combat per the rules covering multiple targets in Appendix Six of the main rulebook. Therefore, in the example above, the charging unit is forced to stop 1" away from the additional enemy unit.

No. The updates in Warhammer Chronicles replaced the wording on pages 54 and 55 of the rulebook in regards to flank and rear charges involving single models. Anything larger than a man sized character on foot now has a clear front/flank/rear for combat purposes and his opponent will get the flank / rear bonuses if the model is charged in the flank / rear.

Yes. As outlined in the Charging rules, the first rule of charging is to bring as many models from the charging unit into combat as possible. As "fewer" is greater than "zero", Unit A must perform the wheel and complete the charge.

No. When charging, move single models exactly like other units, except instead of the single wheel allowed, the model may be rotated once in place for no movement penalty. In other words, single models can only change direction once when charging.

Simply move the chargers off the table and then allow them to return next turn, in the Remaining Moves phase, as normal.

As long as you're not charging, you can change the position of a character, though he must still remain in the front rank if possible (except for Skaven...).

I always play it that the unit has to physically move on to the table, as if its front rank started the phase touching the outside edge of the board. This isn't directly supported in the rules, but is the intent.

It arrives back on the battlefield when it would normally move. So, most units would arrive back on the battlefield in the Remaining Moves phase (as they cannot charge). Units like Spawn of Chaos will arrive back in the Compulsory Moves phase (otherwise they would never actually get back onto the table!)

Correct! This also happens to deep infantry units, with enemy units close by that stop marching.

Move the unit back on as close to the position it left as possible.

Yes.
