Nothing wrong with the history lesson, but to be clear most of that was 80+ years ago, or in some examples 200+ years ago. Y’all talking about uboats and the war of 1812.
Modern naval war is fought at the 10 to 100s of miles range, if not thousands in the case of some terrible, terrible armaments in some of the boomers. Hand gun battles are just not realistic instances in the modern world of naval warfare.
It’s a bit akin to why the Navy also barely teaches you how to swim. You get one 30 min class in boot camp, and literally no refresher courses or further training ever. If you have to swim in the modern Navy, you are already dead.
