Water is not kind to bullets, especially fast moving rifle bullets.

Hitting water with a bullet may shatter the said bullet or even cause a ricochet. but some of the shots should still penetrate the water.. but not all

As the other posters have said, water stops bullets very fast. However, shooting at low angles can result in the bullet ricocheting, like a rock will skip along a pond surface.

NATO 5.56 rounds can go throw wather for 30/40 meters without change direction.. it's projected for that..

Just search for the mythbusters episode when they test how far bullets can travel when shot from land into water. Even a 50cal stopped within 3 feet (about 1 meter)!

I know this is irrelevant, but I had no idea people could have a typing lisp until I saw this issue.

Srsly.. wth is a waith wather? Water is very effective at stopping traditional bullets but hitting the apex of waves would not do this... if that's what he's saying?

otherwise yea, a few feet of water will completely stop a bullet usually

I added a pic showing a pistol round being fired while submerged. The round can be seen at about 1.5 feet and completely stops moving forward about about 2 feet.. doneskies

I don't know where you get your info but a snow drift will stop a bullet in a couple feet unless it's a FMJ Bullet which are illegal for use in war.
Water will slow a regular bullet to non lethal speeds way way sooner than 40-50 meters. I'd feel perfectly safe behind 5 feet of water. No way a bullet will go through that.

But he specifically said 30/40 meters of wather... WAY different

Rick added a comment.Mar 9 2013, 1:54 AM

I'm assuming he means water unless wather is a guy and he stops bullets by waving...

Rick let's google this: "NATO 5.56 bullets", you will see on wikipedia that they are FMJ.

A pistol will go further than any rifle round because it is much slower. I don't see any problems here unless you're firing 9mm and it's not going through.

Wave is 30-40cm width not 40 meters! is impossible to stop a FMJ gunfire!

FMJ or not dosn't have much difference. If we forget about gravity, bullet traveling in fluid (air/water) will be slowed down by a drag of said fluid, which depends heavily on density of fluid and speed of a bullet, school physics btw. That's why just a couple of meters is enought to stop bullet of any caliber - it's speed generates huge drag, which can actually destroy bullet. For the same reason, bullets/ammunition designed for underwater usage has exitspeed several times lower then of a typical pistol.

Fixed the title and description.

ViiK NATO 5.56 bullets is designed also around this issue, a wave cannot stop the bullet, it will result lower but will forward.

When bullets hit water, they decelerate so fast it causes the bullet to shatter within a foot or two of the body of water. This was already proven by in live video on that TV show Myth Busters with a number of rifles. I believe one even included a .50 cal sniper and it didn't even do the best.

even if a bullet goes trought 10 inch of water, it will no more kill, you could catch it with your hands...

maybe it should stop them after a foot, but i saw the mythbusters episode and water does not like bullets. that's why there is an underwater gun in this game.

If you don't have the underwater gun, toss a frag/grenade in the water. Works for me. ;-)

(I stated this within Duplicate Bug #5736)

This is an issue.

Bullets can't travel far once they hit water, but currently in the game, if you're 0.00001 nanometer below the surface, you're safe.

Just add a hunting bow and arrows to game and give them possibility to move 5-10 meters below water surface and you get divers panicking.

At the current AI level, or the last time I played as a diver, the minute I surfaced or fired one shot I would immediately be fired upon much too accurately.

So not really complaining about the reduced velocity of rounds. More worried about the ability to perform stealthy sniping after water insertions. ;-)

Water will stop bullets. Complaining about waves stopping bullets is just as aimless. Additionally, the 5.56 Nato round in not rated to travel 30-40 meters underwater and neither is any other standard rifle cartridge. Even if some rounds manage to penetrate the surface of the water, we are unlikely to see any severe damage from that bullet as it'll be dropped to less than acceptable velocities almost instantly. Doesn't mean you can't shoot for the mouth when they pop out ;) I think this has been discussed enough.

"This is an issue.

I agree, we still would like to see that bullet goes like half a meter under the water with bubbles as a trace behind. No damage, but the visual.

Sure mythbusters proved that bullets won't go far into water, but that was at point blank range. Maybe they would have had a different result if they shot from a couple 100 meters? Not saying they will travel 30-40 meters, but I think the test with the .50 cal would have ended differently if they hadn't nearly stuck the barrel into the water :)

If I'm not mistaken, velocity of the round significantly decreases after exit from the barrel. In order for a difference, the barrel (at point blank range) would have had to be touching the water.

Lol. You guys are all looking at this from a non submergeble weapon like The M4 or M16's. Both NATO and US forces have spend lots of money in the development of projectiles that can travle trough water for a decent distance before changing direction drastic. H&K has plenty of prototypes not to mention THe russians have made harpoon/assault rifle hybrids. Guns wit normal 5.56 rounds instad of normal bullets the Use Long 10CM rods in the front harppon like. THese projectiles travle at high speeds underwater for bout 50 to 100 M before losing speed and tajectory.
Sorry for my bad english but again underwater projectiles have been made. and do work.

Considering that we have a SDAR which shoots underwater, is a discussion on realism actually relevant here?

Tolya added a comment.Jul 8 2013, 1:34 PM

My point is, since SDAR should (haven't tested this) shoot out of the water, whether bullets should have some sort of water penetration is a question of gameplay. If bullets cannot penetrate water at all, but SDAR can kill targets by shooting from underwater, then it creates imbalance, since a diver can kill a soldier on the shore, but not the other way around.

Exactly. Actually Soldiers are not able to shoot divers 1 M underwater. I was underwater when the Opfor car started shooting with its MG didnt hit me at all.

Exactly guys, but there are people that think something like "i watch mythbuster i know everything" that downvoted the feedback, i hope BIS is more smart than them

Lol exactly. Note that mythbusters didnt used the special ammo simply because they couldn't get theyre hands on it.

As mentioned "Bullets can't travel far once they hit water, but currently in the game, if you're 0.00001 nanometer below the surface, you're safe."

I am getting exactly the same results. Playing the diving showcase, I am safe poking my head out of the water, because only a well placed headshot will get me, but bullets landing right infront of my face, which I gues should be hitting my chest, nothing...

Second encounter was the heli showcase, was hovering above water shooting at an enemy swimming in the water, wasted 1000 rounds shooting right on and around him, and nothing at all.

Bullets should have some form of damage, at least up to one meter in depth. Even if it halves the total value of damage given, it should still have some effect.

hey author, i think you should test it. get a gun...any gun and a clay target.
put clay target in 6in of water perhaps a puddle
then submerge loaded gun in water.
take gun out of water and get about 5 meters back and shoot clay target.
if clay target breaks and your gun doesn't malfunction try a foot of water and repeat.
then report back with video evidence and that should prove everything to everyone. thx.

disclaimer: i am not responsible for anything that may happen to you during this experiment. thx again

@anderson: In my country, is illegal to hold a weapon, and I don't have the motivation to ask a permission for that

Just to make something clear:

  1. Firing a bullet within the water it can travel several meter in RL. Mostly special ammo is used for that purpose with 5.56mm effective range at about 10-20m.represented in the game with the SDAR and Dual Purpose ammo.
  2. Firing a bullet at a water surface is like firing it at a rock. the faster the bullet goes the faster it gets destroyed. Still you have about 1m depth where it can hurt(not much though). Thats something missing in the game.

3.Firing out of water is absolutly possible since the bullet just loses some speed in water and then travels with lower speed in the air. To achieve a good effect its important to fire the weapon as close to the surface as possible. Its possible with the SDAR.

So at all this ticket has left point 2.
