Impossible to tell what ya need clarification with GMan.
Lets say the War is five weeks long. At the beginning of first week, planes are assigned by staff, and objectives given to the sides. At the end of the week, the side achieving all of their and/or more objectives than the other is declared a winner. Air to Air and other types of "Combat scores", mean nothing.
Now there is a Master Plane set given by the Staff before the War, which encompasses the entire set available throughout the five weeks, including transport, AAA and other vehicles as well. In order, Early to Late war production.
The side that wins week #1 gets to pick (4) new "rides" GV's included, to go into the next week (historical rough equivalent of a year or so) with. The losing side of week #1 only gets to pick (3) new rides to go into week # 2 with, simulating the fortunes of war, on production, economic base and man power etc...
This continues for five weeks, regardless if one side sweeps in three. Best out of five "Wins the War".
Dat help?
