Attention! Read this before proposing a "trivia"!

When proposing a trivia, please remember to:

Sign your posts by typing four tildes (~~~~). This will automatically leave your username and a timestamp, so we can tell who you are and when you posted.
Preview your edits to prevent formatting glitches.
You can indent your posts by putting colons (:) at the beginning of each line. In long discussion threads, this can help separate comments and make it easier to tell who is replying to who.
Make sure it's readable.
Identify what category it is in. Make sure to attach <font color="Gold">CATEGORY HERE</font>.
- Please note that the DYK will be separated into five groups; Characters & Groups, Events & History, Technology & Locations, Weapons & Vehicles and Miscellaneous.

...that the UNSC Air Force and UNSC Army occupy UNSC territory as defensive forces?

...that the history of the Covenant is depicted in seven murals in a deleted scene?

...that humans must use a chemical known as cytoprethaline before entering cryo chambers to prevent ice crystals from forming in their cells?
