You should not know exactly which mission you will be playing when you pick your force. To choose the mission, roll a D6 on the mission table at the start of the appropriate scenario section. Make the roll after you have set up the terrain, but before you begin deploying your forces. If you and your opponent agree, you can simply choose a mission instead.
Summary
- Choose scenario (use strategy rating if desired).
- Decide who will be attacker and who will be defender (use strategy rating if desired).
- Choose your army, using the force organisation of the chosen scenario.
- Randomly determine a mission to play by rolling on the appropriate scenario mission table.
- Get fighting!
