nope.
the code will assign some reingorecement mech units and armour in a generated battle for the AI.
Some badly-sructured units were not loaded correctly, so you could get a spare passenger with reinforcement status loaded into an on-map carrier on turn 0 - that has been fixed.
(It can also be done by scenario designers who put passengers with reiforce turn set into on-map trucks as well, but that one is human error
