You misunderstand how the unit is set up

The German motorcycles units are single Icons that represent 3x beiwagenkrad (sidecar bike)

The collective total of passengers carried by those three beiwagenkrad ( Kradschutzen) is 6 men = 2 per bike

When you dismount that unit it contains 6 Kradschutzen so those 6 men represent the one in the sidecar and the one behind the driver X 3

The crew/drivers of the beiwagenkrad do not dismount which means the three beiwagenkrad that make up that single unit have three drivers that are free to move their beiwagenkrad while their passengers engage in combat

This is why when you click on a beiwagenkrad that has been dismounted by the Kradschutzen passengers it shows 3 crew...... those are the drivers of the three bikes and not the passengers

The horses have been well explained by others

Therefore nothing will change

Glad you like the Bike set up , it is much better than the original kludge
