In Nuuk in game 1,071,718 I had a destroyer guarding a landing point. Around 30k troops came in to land and I was happy with that as the devs said that troops in ships cannot fight. When the troops ran into the ship, they sank it. I am pretty sure that some tanks and troops sitting in cargo holds can do no damage, especially to an armoured, heavily upgraded destroyer. I have some pictures of the fight during and after it.
