MODERATORS
I was envisioning dolphins trained in tank warfare. The First Armored Cetacean Division.
If dolphins can be astronauts they can command a tank.
yeah, I support the troops
Water transmits sound much better than air, so the shockwave from any explosion (possibly including the tank's own gun) would rupture the eardrums of everyone inside.
Skill Issue.
Yeah, just don't get hit
They travel further, but higher frequencies slow down due to the medium.
It'd probably muffle some of the more damaging high frequency sound waves but there'd be some shockwaves of lower frequencies involved which might do something else to you
No, the speed of sound through water is essentially independent of frequency. Sound is a compression wave.
You're thinking of transverse, or surface waves: https://www.youtube.com/watch?v=95sQcSulRFM
Given the high amplitude and nearness to the gun I'd guess nonlinear propagation would play a big part so that's interesting. IDK if that makes for a more intense shock front.
I was under the impression that high frequencies don't propagate well through water, but that's dumb because sonar exists lol.
Blame it on lack of sleep
yeah but if it transmit sounds better that means you can also hear better so ruptured eardrums aren't so much of a problem. basically a 0 sum thing
they should do this but with submarines
They could finally use screen doors!
If you put enough life plants and filter media in, it becomes a miniature ecosystem and you can poop in there
I mean a modernized Abrams already weighs 80 something tonnes so how much worse could this really be.
Add Sadam and re upload
But have you considered... the Piss Tank?
dying instantly as an external explosion causes a shockwave in the water that ruptures everyone's organs
Fun tank fact! Due to a tendency for the M4 sherman to explode into flames when hit in the ammunition, it was devised to stow the ammo in water, coining the term "wet stowage"
we mwust stowe ouw ammow in wet stowage uwu
So that's where that comes from! I'm always telling my friends about my wet stowage, now I know
that is a fun fact though, thank you
This is literally just Evangelion
Get in the fucking Merkava Shinji 
This is just a reverse submarine
Makes me think of Metal Gear Solid: Peace Walker where the mech's cockpit fills with water for some reason
Any ambulatory mecha would have massive motion sickness issues for the pilot whenever it walked. Suspending the operator in a fluid would possibly dampen the effects of bobbing around on the vestibular system and dampen shock from collisions or high-G turns. At least I imagine. I haven’t played Peace Walker but that’d be my reason for that to be in the design.
Huh, that actually makes sense! It's worth pointing out that it also allows for a woman to be piloting said mech in a bikini and Kojima has terminal coombrain so that might factor in too lmao (maybe I'm not giving him enough credit idk)
It's not even a bikini it's just underwear. So...yeah, fanservice, just fanservice, albeit with an in-universe explanation as what Southloop said is pretty much it.
In Peace Walkers defense, you can also go on a swimsuit date with Kaz and get hot manbod so at least it's somewhat inclusive
this is why mecha need to be smaller, agile, and well-coordinated, like a ballerina or someone taking that rich person ettiquette book-balancing-on-your-head-as-you-walk class, rather than a huge stompy brutish thing almost falling over with every step (looking at you, battletech)
breathing is for losers

What about the watermelon tank?
