Although the Call of Duty Wiki is a large database, there are some items in the series that are more notable than others. The following are some guidelines about what can be covered:
- Explicitly major items from the Call of Duty series that can be identified by everyone are covered. (ex. Call of Duty 2, Shepherd)
- Anything that the player has distinct access to is covered. This includes weapons and equipment. (ex. Mk 19, Breaching Charge)
- Articles that are specific to their subject take precedence in notability. (ex. Pripyat over Ukraine)
- Countries that play a major geopolitical role in the series are notable. (ex. United States, Russia)
- Article precedence still applies. (ex. Imperial Japanese Army over Japan)
- Events, places or people that are referred to across more than one level are covered, provided they do not consist of large amounts of real life information. (ex. Zakhaev International Airport, Russo-American War)
- Characters with a fixed name that are either consistently seen in a mission or have roles that extend across many missions are notable. (ex. West (USMC), Ryan)
- Characters who are mentioned in non-battle chat are also covered.
- Vehicles that play an active role in a mission are covered. (ex. Mi-24, Zodiac)
- Real-life articles must have some pertinence to the scope of the wiki. (ex. Josh Olin, United States Marine Corps)
- As a general guideline, articles on subjects that can be explained in two sentences or less are not notable and do not require a separate article
Anything that falls outside this criteria is subject for either speedy deletion or being nominated for deletion at Articles for Deletion, depending on the situation.
