I just finished watching Greyhound with Tom Hanks. Pretty solid movie. Liked all the detail it went into. It felt authentic to me. What I didn't like was how the Germans can be heard on the radio taunting the Greyhound ship. We get it, the Germans were the bad guys. But it got me thinking, was it common for ships/submarines to break radio silence just to taunt the enemy? Seems rather foolish, but what do I know. Thoughts? Thanks!
