The corpse grinder cult icon wargear states that "If the fighter carrying this icon is standing and active they can make the following action: Enrage: All friendly fighters..." It doesn't state whether this is a basic or simple action. It also doesn't state the action is free. What is the general feeling around this? I can if this is costing an action it quickly becoming useless as the bearer gets left behind, but I can also its application being clutch at certain moments. I'm inclined to lean towards its use costing an action but i'm interested to hear your thoughts.
