All rules are p.20 and 22.
In the diagram shown for case 4.1.,
you have, from left to right:
DR1, "A", "B", "C"
and in front of A, B and C, you have DR2
Suppose "A" charges. DR2 maintains.xFallenx wrote:Can you explain how # 4 works? If I was the General of the opposing army, ie controlled the three units, I would charge with the unit pinned between the two unit of DR. If you held, or chose to flee, I would just move the remaining two normally once you stack your DR to take the charge. I absolutely don’t see how the southernmost unit of DR is going to affect much more that the march movement of the center unit as the charged unit is rubberbanded into combat with the westernmost unit. If you flee, then both of the units would be able to march normally. What am I missing, please use BRB pg numbers for reference on which rules come into play here.
A has some constraints and some freedoms about charge movement, which is to move forwards, make 1 wheel, move forwards, and the end result must maximize models in contact (p.20) and must allow to close the door if possible (p.22).
Here, no matter the distances and the angle he selects, there will be only 1 DR in contact, so maximisations results in 1.
You question is why DR2 don't have to close the door? It is because there is a possible way for A to charge and to close the door. Therefore A must use that way (see p.22).
As a result, A will have closed the gap by itself, and will be in contact with 1 single DR (which allows to kill them all, still).
With this situation, B and C remain blocked, the best they can do is to charge the DR themselves.
Overall, the argument is that if there is a way that A can charge and close the door, A must take it.
Only if there existed no possiblility to close the door with charging unit, (including taking a different path for the charge), then DR2 would have to close the door.
