Implementing gender-based messages for various states of soldier in battlescape.
Some languages have gender-specific morphemes for verbs in past simple.
For example, in Russian we have these different sentences:
  - Анна Иванова потеряла сознание ("Anna Ivanova has become
    unconscious", female name)
  - Павел Иванов потерял сознание ("Pavel Ivanov has become
    unconscious", male name)
