The SC has a sequence of play with notably differences if compared to USE.
1. Strategic Phase (it is done by all players)
a. Collection of MSPs
b. Strategic Naval Phase
a. Axis Organization Phase
b. Axis Strategic Bombing Phase
c. Axis Movement Phase
d. Axis Combat Phase
e. Axis Follow-up Combat Phase
f. Axis Strategic Movement Phase
g. Axis Political Phase
Same structure as for the Axis
It simply involves victory conditions check, return of naval units from sea zones to ports and move air units from Front Air Boxes to the main section of their Front Air Box.
Note that in USE the combat and movement phases are integrated and here both phases are sequentially played
