Germany had radar letter in the war both air and naval.
In phase two we may apply a structure to turns to assign a timeline to the game in order to get things correct with respect to when certain events can occur.
I think 6 month turns are the correct “distance” to assign thus:
1. JANUARY-JUNE 1942
2. JULY-DECEMBER 1942
3. JANUARY-JUNE 1943
4. JULY-DECEMBER 1943
5. JANUARY-JUNE 1944
6. JULY-DECEMBER 1944
7. JANUARY-JUNE 1945
8. JULY-DECEMBER 1945
or you can do this:
1. January - April 1942
2. May-August 1942
3. September -December 1942
4. January – April 1943
5. May –August 1943
6. September-December 1943
7. January - April 1944
8. May-August 1944
9. September-December 1944
10. January – April 1945
12. May –August 1945
