Template:Hidden gun category
From Gunsopedia
This template is meant to identify the numerous firearm categories that gun pages should be included in but do not need to be included on the page itself. Indeed, some firearms can be listed in dozens of categories, making easy reference from the page bottom of the article in question all but impossible.
Appearance
Note: This is a "hidden category" that does not appear in the category list of pages assigned to it. This is done to prevent massive clutter at the bottom of the pages in question.
[edit] Usage
This template should be placed in the category that is not to be displayed, not on the page for any firearm, and should ideally only be used by admins.
