Well, I was wondering. What are those crosses in the top of the flag when we visualize military battleplans?
For instance, take a look in a map of the Battle for El Alamein:
The Free French division has one cross, and the italian division right on the side, has two crosses. What does it means? We can also see the same in the following map of D-Day operation at Normandy.
If you have some references, better.
