If a troop or general does not have splash damage and deals 500 damage against a target with 100 hit points, it kills the enemy and no other. If the troop or general instead has splash damage, the damage dealt will kill the first target and the 400 remaining points will carry on to the next target in order.
All of the CoA generals and MMA have splash damage and Nusala gives splash damage to troops she carries.
The Juggernaut skill will just increase the generals own attack damage, which when paired with splash damage will kill additional troops when he strikes. Since the general already has splash damage, the chance of adding splash damage to his attack via juggernaut will be irrelevant.
