Initiative Order

(Rule)
Description: Melee Attacks are performed in Rounds of Combat during the Melee Phase. All Melee Attacks have a specific Agility value that corresponds to the Agility of their model part, unless specifically stated otherwise (such as Impact Hits or Crush Attacks).
Each Round of Combat is fought in a strict striking order, referred to as Initiative Order. The Initiative Order in a combat is determined immediately before any attacks are made. Take into account all modifiers that affect the Agility of attacks that may be performed in this Round of Combat. Once the Initiative Order has been determined for a Round of Combat, it cannot be changed by effects that alter the Agility of attacks during that Round of Combat. The order starts at Initiative Step 10 with all attacks with Agility 10, and is resolved downwards to Initiative Step 0 with all attacks with Agility 0 or less.
At each Initiative Step, all attacks from this step that meet the necessary requirements (see which_models_can_attack, below) strike simultaneously.
