Each Monstrous Infantry model on foot with the Ogre Charge special rule that successfully charges an enemy has the Impact Hits (1) special rule. Models with this special rule that are part of a unit with ranks add their current Rank Bonus to the Strength of the Impact Hits they inflict. In addition if, when calculating the charge range, the two highest dice score a total of 10 or more, each Ogre inflicts D3 Impact Hits instead of 1. This aside, the normal rules for Impact Hits apply.
