One new feature unveiled about PS2 is the mission system. This is a multi-layered approach to provide players with a sense of focus. There are automatically generated missions, although the main focus is on player-generated missions.
The most basic missions will be automated.
Squad and Outfit missions
Squad Leaders and Outfit officials will be able to arrange missions.
Entire Empire-wide missions have been confirmed. It is possible these are arranged by high-ranking players with the right certifications.
The ability to create missions is a trainable skill. It sounds like there is a leadership focus available through the normal skill tree. This suggests (although not confirmed) that this replaces Command Ranks.
