===Tense===

A rule of thumb is to use present tense in all cases. For example, articles for missions, activities, non-player characters, etc. should be written in present tense. An exception to this rule would be events that have occurred in the past, or for in-game content that has been removed. For example, previous years' holiday events that have already occurred should be written in past tense.

* '''Past tense:''' Past events and history regarding official service
* '''Present tense:''' All other cases
