Yes, that is correct.
You can always use your trannies as fodder, both in attack and defence, even if it dont have any attack-value.
Can transports be taken as casualties during a amphibious assult?
No they cannot, because they aren’t technically “involved” as far as the trading of ammunition.
Exactly. If the sea zone is clear, their job is done.
thanks
If a battle occurs before the assault then yes they may, but their cargo goes down with them…
