From Halopedia, the Halo wiki

A Disambiguation page is used on Halopedia when one word can link to several articles with similar names. Disambiguations are used as navigational aids to allow users easier access to all pages that they may wish to access. Disambiguations vary in how broad they are, as some words, like "Rookie", only link to three possible pages, while more common words, like "Rifle", can have many more meanings. It is incredibly helpful to Halopedia that as many disambiguation pages are created as possible so that typing in any word on the "search" function will yield easy to read results.

Disambiguation pages are denoted by the "disambiguation" template:


This template states the following:

This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. If an article link referred you here, you might want to go back and fix it to point directly to the intended page.
