Category talk:Cruisers of Japan

organization
Cruisers are listed directly in Category:Cruisers of Japan and indirectly through its by-class subcategories. Also certain of these same cruisers are directly in Category:Cruisers of the Imperial Japanese Navy and indirectly through its by-class subcategories. Is there some purpose in this duplicative structure? Hmains (talk) 17:59, 24 January 2009 (UTC)
