User blog comment:Wildoneshelper/My reasons to put "artillery", "cavalry" categories into units riding elephants/@comment-127769-20140205124106

The problem whit this kind of categoriziong articles is the overcategorization, I think is better to create navigation boxes to solve these probles anyway. giving an article just one or maybe two subcategories that includes clearly what kind of unit is helps to resume many categories, for example cavalry archers. all cavalry archers are both cavalry and archers, resuming these two categories in one solves in part the overcategorization problem in many articles.
