Alpha Strike Commander's Edition p. 137-139 details advanced buildings. Additionally, p.74 notes that "Advanced buildings will have their own unit card and, if armed, can make attacks as a normal unit."
Does this mean that armed, advanced buildings show up in the initiative order like other units? (If so, do they have any special differences when using formation initiative? (p.33) ) So, can the player simply declare that they've "moved" their immobile building, and kick it back to the other player to move their next unit/formation?
Or, since buildings can't move, do they stay out of the initiative process?
