Here it is worth talking about Royal heirs, the technology that reduces the damage taken by camels and shotels from mounted units. Definitive Edition implemented this by modifying the damage formula, to allow for negative values. In the Community Patch, we had to be more creative.
Because of this technology, the melee and piercer armor classes are split depending on whether the unit is mounted or not. Mounted units use class 40 for melee and 39 for pierce, the rest of the units use class 4 and 3 respectively. All units have the four classes in their armors so that they can take damage from everyone.
With this, the Royal heirs technology simply increases the armor against mounted units for the affected units.
