But what would be the role of a chariot (not to forgett, a family member's chariot in case of the Casse) in a siege battle? In assaults on towns you need two things: missle units for the preparation fire and decent heavy infantry (quality of classical hoplites at least) for the fight in the streets.

Chariots need a lot of space to deploy and manouver, so their only role can be to throw javelins across the wall before the assault. And for that there are much better units in the Casse army. Any participation of them in the melee will by guarantee lead to the loss of the unit and the death of the family member. Before replacing their bodyguard with Rycalawre I had lost all FMs that took part in siege battles.
