I have not only watched a couple of IJN destroyers shoot themselves in the stern (so to speak), but have also recently witnessed a D3A 'Val' dive bomb and badly damage an IJN Akitsuki class DD that was stalking me, such that I could polish Mr Akitsuki off with a torpedo. 'Twas most enjoyable...
Oh, and there was the time that I intercepted a task force, destroyed a Soyru class CV, plus a Kongo BB and, in the subsequent pandemonium and confusion, watched a Nachi class CA ram and sink an Asashio class DD that blundered into its path.
