1. Let's say I have 2 missile units fire at 1 defender in good order. The first attack disorders the defender. For the 2nd attack do I use the disordered column or since combat is simultaneous do I use the normal column again since that was the state of the defender at the beginning of combat?
Per 11.2 Active units fire once at any point during its movement. For foot missile units the act of firing ends its movement. So the first missile unit would fire, if that attack Disorders the target, then the second missile unit would fire on the Disordered column.
2. Can I do the following in this order?
- Have an archer fire
- Move an archer then have it fire
- Move a knight, then have it charge a target based on the results above
Or must I complete all movement before firing, shocking & charging?
Per above, firing is part of movement so steps 1 and 2 are fine. The Shock Phase follows all movement (per 4.0 and the extended sequence of play), so step 3 is also fine as long as that Knight is the last unit to move.
