  The gun isn’t for what’s outside.

  If the gun gets wet down there, it’s already too late to serve its purpose.

    I know the joke is that guns are pointless in the hadal zone because cthulu lives there, but…

    A gun being wet or immersed in water rarely makes it torally incapable of firing at least once.

    Many modern firearms will fire a projectile at lethal (to a human) velocities while underwater, though range and accuracy will be greatly reduced.

    Getting a gun wet does not make it ineoperable.

    The primer and gunpowder combust and deflagrate without the need for external atmospheric oxygen, they contain their own oxidizers.

    The main problem is that if the gun’s barrel is full of water, this provides significantly more resistance than a barrel full of only air.

    The cartridge will fire, but the bullet’s velocity through water will be much lower, the weapon might not cycle its action properly (meaning you may have to manually do so)…

    … and the overpressure will cause significant damage to the weapon, possibly leading to it explosively dissambling itself after sustained overpressure usage.

    Which is actually comparable to running a bunch of overpressure, magnum + rounds through a firearm above water.

    There exist firearms and specialized cartidges (flechettes or otherwise) that are designed differently to operate consistently while underwater, as well as ‘amphibious’ firearms that work decently well submerged and not submerged.

      Although if you’re deep underwater and your gun gets “wet” its probably because whatever kept you from being crushed into a pulp just failed.

        I’m sure navy seal teams are trained for aquatic fire fights. But the chances of any of them interacting with aquatic guard units are probably slim and if any have happened, are going to be classified.

      Tbh i was mostly thinking of the limited range underwater. still remember the mythbusters episode where tried that and the bullet was fully stopped after like 2-2.5m
