Thanks to a minute trace, Gao Yuan and his team had obtained a lot of information.
A real military map details even the length, width, and load capacity of a small bridge that might seem commonplace and unimportant for a map, like one you'd find in front of your home over a small river.
During World War II, German military maps, especially those of domestic use, were so detailed that they included the layout of every single house in a town and even the exact location of wells in backyards.
If they had such a map, Li Jingang could have been familiar with all the buildings, rivers, roads, bridges, and lakes in an area he had never visited before. That was true for every qualified special forces member and anyone who knew how to read a military map. That's the significance of a military map.
Gao Yuan and his team had no military maps, only large-scale civilian maps and printed satellite photos.
