What are the campaign objective types (Personal, Faction, Alliance)?

Each campaign chapter offers three families of objectives, which gives you several ways to progress:

• Personal objectives: what you do alone (beating defenders, dealing siege damage, conquering targets). You control these directly.
• Faction objectives: completed by your whole faction (e.g. control X capitals). You contribute, but it's collective.
• Alliance objectives: carried by your alliance (e.g. eliminating enemies, taking seats together).

The consequence: even on a day you barely play, your faction and alliance keep pushing their objectives forward. Conversely, your active contribution helps everyone.

Tip: look at which objectives your group is close to completing and concentrate your actions there — it's usually the fastest way to unlock the chapter reward.
