Calves.
Calves are warriors, but they DO NOT count for rule nor hits in battle. They will simply be referred to as calves from here on out. They can be removed from the board in battle, but they CANNOT be moved individually, either by yourself, or enemies (for example using force). They must always move with a female where possible. If no females are present, then they must move with males. They always move 1 for 1, i.e. to move 2 calves there must be 2 warriors to accompany them. If you ever have to move 2 calves and there is only 1 warrior, the other calf is left behind to die ☹️ (remove it from the board). In battle, your pieces are removed in the following order:
i) warrior (male or female, you choose)
ii) calf
iii) warrior (male or female, you choose)
iv) calf
Etc etc, then
v) tokens when there are no more warriors or calves left
