I see what you’re saying, but what about pg. 11 of the rulebook that says, “You can move units into friendly spaces en route to hostile spaces during this phase, but they can end their move in friendly spaces only during the noncombat move phase.”
Doesn’t both the TRN’s moving to amphib assault and the BB to provide shore bombardment violate this rule, since they are ending movement in a “friendly” sea zone (i.e. one without enemy ships)?
