I keep on stumbling on this very simple point. Fire is in the reaction (first) phase. French turn (not defending) has target, can it fire this turn and then charge in activity (third) phase at the same target. I suspect this is ok, but the wording in the QRS always confuses me, as it says under sequence of play: DEFENDING UNITS take reaction, but on page 41 it just says you can fire "when your unit has a target in range".
Sorry for such a simple question.
