I believe I've understood most of the rules, but one section looks very confusing to me, probably because of the language barrier. It's Combat Reform (p.55 BRB)
Most confusing to me is not the text in BRB itself, but the amendment given to it by Official Amendment in 21st July
I suppose that it tells us "Your unit cannot teleport from enemy's front to its rear nor any flank." Probably, GW added the restriction because it must add the text, "the centre point of the reformed unit does not have to stay in the same place," to allow reforms to widen the frontage of unit. (Keeping the center point at the same place would always makes unit out of base contact with its enemy.)
Well, that's my first question.
I also wonder how the first restriction - "it cannot be used to get a model (friend or foe) out of base contact with the enemy if it was in contact before the reform was made" - works.
Provide that 5 by 5 infantry unit has won a round of close combat with 5 by 5 enemy unit in its flank. The Champion and one Character in the unit is not in base contact with the enemy for whatever the reason. Now the player of the winning unit wants to make his models turn their faces to the enemy. How can he conduct the reform?
Does the first restriction require the player to keep 5 of his rank and file troops and enemy models in the firs rank in base contact with enemy? Does he have to reform his unit into 7 by 3 (+4) formation if he want to make his Champion and Character in base contact with enemy just after the reform?
