In the previous example, what if the British transports had been subs instead? Could they submerge to avoid becoming casualties?
The only time subs can submerge is immediately before rolling dice, whether attacking or defending. In this example, the British subs can’t submerge because they don’t get to roll dice (they’re not defenders — Germany is defending, the US is attacking, and the British are just innocent bystanders caught in the crossfire).
