TemplateDoc:Acronym/Official

Usage
This template is used to sanitise Halopedia official and reserved acronyms before they are used in other templates. It does not guarantee that an acronym is valid, as the correct response to an invalid acronym will vary between templates that call this one. However, it guarantees that what it returns will be in lower case and that, if it was a valid acronym, it will have been replaced with the primary acronym for that topic. This allows template pages to only have to consider the primary acronym cases, while still providing support for the secondary acronyms.

Usually, if no acronym match is found, the template will simply return exactly what was passed to it, albeit in lower case. However, by setting the  parameter, the template can be made to output nothing if the acronym does not exist.

Error states
