What important military status does Czechoslovakia have?

Czechoslovakia is located in the center of Europe. It not only has a developed military industry and rich mineral resources, but also has a very important strategic position. After the Germans occupied the Czech Republic, they could use it as a springboard to attack the Soviet Union eastward and attack important British and French positions in the west, so Germany had long coveted it. There are a large number of military construction sites in the Sudetenland region of the Czech Republic. If the Sudetenland region can be obtained, conquering the Czech Republic will be effortless.
