ok guys, so I have a question regarding charge reactions that came up in the slamwich. the example was I had a unit of halberdiers that had held against a charge against a unit of ironguts. The stonehorn then declared a charge against the same unit and I decided to flee. The stone horn then gets a chance to redirect. The question is whether the first unit of ironguts gets a chance to redirect. my interpretation was that when you declare charges you do it by unit. When a unit finishes declaring its charges, you move onto another unit and it does not get to later change its reaction.
Can someone confirm or deny this. We had the T.O. come over and confirm it but while looking back the rules are a little ambiguous. (typical gw)
