I’m not sure I’m grasping your question correctly. HBG offers many different sets of combat units, and most of these sets are available in a range of colours. The HBG website allows you to display the available choices either sorted by country or sorted by colour. In terms of the models – meaning the physical shape of the units – some of the sculpts represent troops and /or equipment from the major A&A nations, while some represent troops and /or equipment from various minor nations on the Allied side, on the Axis side, or from amongst the neutral nations. The page for each set includes a list of what units it contains and what nations they’re from, and also what colours they’re available in. Generally, the colours fall into three groups: colours that match the current out-of-the-box ones from Global 1940, colours that match earlier ones from earlier A&A games (like the cherry red colour used by Japan in the original A&A PAcific game), and colours that are entirely original to HBG. The page for each set will sometimes include suggestions about what minor countries might be represented by a particular colour, but they’re only suggestions; I don’t think there’s any single comprehensive list implying that such a design in such a colour necessarily denotes such a country. Nor are the suggestions mutually exclusive. The page for the WW2 Japan Supplement Set, for example, suggests that the “Japanese Red” version of that set could be used either as a supplement to the original edition of A&A Pacific, or to depict veteran Japanese units, or to depict Thai units…and the next line below immediately offers the alternate suggestion of depicting veteran or Thai units using the light rose version of these pieces. So there no “one right way” to depict minors using HBG units. You simply check their site to see what’s available and you choose whatever design-and-colour combinations appeal to you.
