At the bottom of the template page, it has a list of the parameters that are valid. Parameters are the items that have the '|' followed by the name and then =.
That template should only have category, description, image, rank and war, not branch or country. The description field is text say you could include the branch of service with that information. If you look at what is being displayed by the template when you are in Preview or Public mode, you will see that the information you entered in the branch field is not being used.
