This is the top or "root" category for templates. Templates should be placed in appropriate subcategories.
See Project:Templates for collated information on templates.
See http://civilization.wikia.com/index.php?title=Special:AllPages&namespace=10&from=!&to=Unit_%28Civ5%29 for templates that might be easily adapted for saving time on this wiki, and see Template:Imp1 unit and its documentation and talk pages for co-ordinated discussion of adapting the "civ" templates for use here based on that template. The second one in the set is Template:Imp2 tech.
