Is this literally the damage score of the weapon, or the amount of damage that the weapon caused on the hit that took out the model?Roll a dice and add the Damage score of the weapon that reduced the model to 0 hits.
For example, a model is taken out by a long rifle (damage 2), the firer has the aim skill (+1 damage) and the shot was a critical hit (double damage). Do you add +2 (the base damage of the weapon), +3 (base damage + aim bonus) or +6 (total damage caused) to the injury roll?
