Information relating any content in articles to real life is prohibited, unless the article is directly related to real life, such as Robert Bowling.
The subject of an article, though it may be based on a real-life topic, should be written from a fictional perspective rather than a real-life perspective.
However, per the naming policy, if a weapon's name is not given/heard in-game, then the real life name can be used.
When editing a real world characters status it is fine to use a real world source to add their birth date, however, unless seen in-game, their death date should not be used, instead they should be marked alive from when they were last seen.
This policy can be overridden by IAR if necessary.
