    I know this is non credible defense, but I would absolutely LOVE a breakdown of all the ways this is a terrible idea

      It might unironically be a good idea except for the increased weight. Also shockwaves from impacts.

          Yeah I thought so too. Besides that, Oxygen running out would be a problem, and perhaps reliability of diving equipment.

          And every operator would need a full one diving suit too, increasing production and maintenance cost.

          Perhaps the tank would rust?

          More fuel needed.

          Electronics would need to be waterproof, otherwise they short circuit, breaking and perhaps harmin the crew.

      The first issue that comes to mind is the noncompressible nature of water. If you’ve ever played in a pool and marveled at how clearly you can hear a digital watch beep all the way from the other end, you can scale this up for any pressure wave. With very unpleasant results.

        Oooh, I see what you’re saying! Yeah, that makes total sense.

        … But couldn’t they just adjust the volume of the heavy metal music all tanks are required to play be the Geneva convention so that full blast isn’t loud enough to cause hearing damage?

          IDK, does the Geneva convention cover the adjustment to pitch so the heavy metal can be faithful to the original while distorted? Source: Harry Potter and that Goblet of Fire.

            I don’t think they accounted for any of the consequences of filling a tank with water. It’s a really outdated set of rules. Like it doesn’t even have special allowances for civilian casualties when Hamas is suspected of hiding in their clothing, which is clearly anti-Semitic. It doesn’t even say it’s ok to kill some civilians if their side embarrassed you by sinking your flagship when they have no navy.

      Any shockwave from firing a shell/active armor/taking a hit would reverberate through the cabin and crush the occupants, not dissimilar to what a grenade does to anyone nearby in a body of water

        Yeah, I remember when Myth Busters tested “shooting fish in a barrel” they found that even if your bullet doesn’t hit a fish that the shockwave will kill them all lol.

      Let me introduce you to Mr Newton. Specifically:

      F = m*a

      To accelerate on a flat terrain (nevermind a slope) you need to apply tractive force proportional to your mass. Water does add a lot of mass.
