For most combat engagements, the battle will begin in day combat and follow the following set of stages. Several stages will not occur unless certain conditions are met. For Event maps, a Combined Fleet mechanic has been implemented which follows a modified combat order. Aerial Combat nodes contain two Aerial Combat phases but no other phases. Air Raid nodes contain a single, incomplete Aerial Combat phase which friendly side planes will only participate in Stage 1 of the Aerial Combat phase.
