Component Types

Each tech in HoI2 has five components and each component has a type. Tech teams have up to five specializations for a component type. There are 34 component types in HoI2. Sadly, it is not possible to add any at this point. However, you can change their appearance and their displayed (not the internally used) name. There is no game mechanical difference between the red doctrine component types and the blue technical component types.

The graphic that holds the pics for the tech types is found at /gfx/interface/tc_icons.bmp. The names for the components are found in /config/tech_names.csv.
