Some modules are in the trees for multiple tanks. For instance: the 2cm Flak 38 L/112 is researchable for the PzII as well as the PzII Ausf. A (as well as a number of others). Researching it in any of those tanks researches it for all of them.

To research a tank you need to research the design in the previous tank. Here's the tree for the PzII, in it the design for the PzIII Ausf. A. Research that and it will be available in the store.
