- The zero value territories are necessary if you want to calculate some of the additional National Objectives.
e.g. the Soviet Union gains 3 extra IPCs if they occupy an original axis/pro axis territory even if it’s worth zero IPC: Sardinia, Sicily, Italien Somaliland;
or the United Kingdom Europe gains 5 IPCs if it controls all of they original territories: Alexandria is worth nothing but UKE won’t get the NO’s 5IPCs if they don’t control it.
But if you only want to calculate the territories IPCs you can delete (or comment for futher versions ;-)) these rows.
2./3. “n” means “neutral”: There are neutral, neutral pro axis and neutral pro allies territories in Global40.
For the insignias: Mr @Tjoek has created some roundels:
