Threat Level refers to how dangerous an enemy unit is. This is measured on a scale of 1-10, where 1 is the level of a Troll and 10 would be a powerful boss from Cartoon Wars 2. Use your best judgement when deciding a unit's threat level, and understand that other contributors may think that the number needs to be changed.
