Maybe I missed it, but I can't see in the rules what happens if a walker that has carry capacity gets destroyed with miniatures inside it. Is it listed in the rules anywhere?
If a unit that is carrying other units gets destroyed / damaged, what happens?
page 54, if there was a unit onboard when it gets destroyed the unit disembarks and gains a reaction counter on it
They've added exceptional air bags to all of the Warfare vehicles, so only an internal ammunition detonation from the Vehicle Damage Table can cause riders a problem, though even that won't stop the vehicle if the damage done hasn't reached its limit.
