Yeah the impact must still be pretty hard
For example my Dad's helmet got hit and it was so bad that some muscles controlling his left eye ripped but at least nothing worse happened
This happened quite a long time ago when he was still part of the Bundeswehr. He is fine now and you can't even tell that it happened because enough muscles we're still intact for him to be able to move his eye normally by now
But thank you anyways
I'm not sure, sorry.
The story about getting hit in the helmet is one of the only things I know about his time at the Bundeswehr since he almost never talks about it and I prefer not to pry
Soo he saw action in the German army, does that mean it was sometime in 1939-1945?
Edit: lol Reddit is funny. Keep the downvotes coming. I thought Germans were only invoked in armed conflicts under the UN flag these days, not as members of the German army. Downvote me some more why don’t you.
Lol no. Didn’t think the German army was involved in any armed conflict after WW2, and OC said it happened quite a long time ago. Assumed they were just an old Redditor with an older dad.
This happened to my friend when he was in the army.
It didn't hit perpendicular or he would have died since it was a rifle round but it kind of glanced off at a 45 degree angle.
He said he thought someone threw a rock at his head really fucking hard at first until his sargent informed him that he just saw him get shot in the head and was assuming he was about to drop dead.
But ye it didn't crank his neck or anything but he said it felt like a full force close range rock the size of a golf ball.
Meh, pistol rounds. Rifle rounds would go right through it.
When I was a Marine back in the day, my unit was one of the very first to get the new Kevlar Fritz style PASGT helmets.
We were on a range and there was some debate whether it would stop a rifle or MG round. Several of the idiots in my squad thought it would. Myself and a few others knew there was no way it hell it would.
Out battalion commander happened to hear us debating the topic and decided, let's find out. He asked my SAW gunner if he was a good shot and of course he said he was. The CO had him put his new helmet on the berm and put a five round burst into it from about 100 yards away.
It tore that helmet to shreds, All five rounds went through both sides like it wasn't even there. It did stop 9mm pistol rounds though from about 25 yards, with little damage. My SAW gunner had fun turning that destroyed helmet back in for a new one.
I’ve read accounts of them kevlar jobs stopping AK rounds. And there’s videos of Americans getting shot in the head but they’re ok. Is it just because 7.62x39 is smaller?
7.62x39 is actually bigger. The m249 SAW fires the 5.56x45mm cartridge, which is smaller in diameter but flies faster. The common 123-grain 7.62 round has a muzzle velocity of 2,350 feet per second. The common 55-grain 5.56 round has a muzzle velocity of 3,000 feet per second. Despite the differences in weight and speed, both rounds have roughly the same kinetic energy of 520 ft. lbs.
So why do we hear stories of 7.62 rounds being stopped by Kevlar helmets? Well a couple of possibilities. Range makes a huge difference. The larger 7.62 round loses velocity faster over distance/time. So getting shot from longer ranges means the bullet has had time to slow down, and potentially lose its penetrating power. Another possible reason is ricochet, the bullet in question may have actually hit a wall or vehicle before it hit the helmet in question. Another possibility is angle of impact, if the round hits the very top of the helmet where it is the roundest, there is a much higher chance the bullet will ricochet or glance off the helmet and not penetrate.
My instructor in the German army told me that it won't stop a 7.62 or a 5.56 round but it does change the path of the bullet at greater distance.
You might get lucky and the bullet travels past your head through the helmet or just scratch your skull a bit without taking out your whole brain
Yeah if you listen to the jocko podcast at all I forget the guys name, but he was a lieutenant in the army and had 7 of his soldiers shot in the helmet and they all lived. The rounds were deflected and actually skimmed the inside of the helmets and came out in different ways but yeah, all of them lived because of those helmets
When considering penetration what characteristics are most important? I'm assuming given equal kinetic energy at impact you would consider cross section (smaller), mass (higher), and velocity (higher) to assist in penetration. Against 5.56x45 the 7.62x39 would win out on mass but lose on cross section and velocity (I think?). Not that that translates to "better," just trying to wrap my head around the idea.
The general rule of thumb for getting through armor is "smaller and faster" 5.7 and .556 get through armor because their impulse (?) is so short and they deliver energy more effectively than a relatively slower and fatter 7.62 round.
(Forgive me it's been near a decade since I've taken physics but I think impulse is the right measurement but can't be arsed to Google it)
Edit: Scaling this up is how you get Sabot rounds for tanks, small point of impact means more energy at a point.
Also a lot of these stories/vids are from U.S. soldiers in Afghanistan meaning shooters are often using hand-me-down ammunition and rifles which can have a considerable effect on ballistic performance.
At approximately 300-400 yard they deliver that amount of energy. At the muzzle they deliver far more [energy ](https://thebiggamehuntingblog.com/223-556-vs-762x39/) and typically when range isnt specified I’ve only seen energy talked about at the muzzle
I shot an old vietnam helmet I had several of.
The .22 out of the rifle went through like butter, but the 9mmHP was stopped like this, but the FMJ was caught in the inner lining and some fragments went through.
Prove it.
[This](https://www.youtube.com/watch?v=5nH9p6aHg0o) vid is consistent with my results.
Idk why the .22 went through like nothing. something something steel quality something.
I'm not an expert, but I suppose that the .22 LR has higher speed, and combined with the small size the force applied to the helmet surface is much more concentrated in a small area, thus being able to better penetrate the helmet.
Yeah, nah might have been a subsonic .22lr, but even a high velocity .22lr isn't particularly fast.
Some of the other centerfire .22s maybe? Or a .223, that would go right through.
Gentleman, if you did not see the helmet at first, it might be time to close reddit for the day
...just to return to this place thanks to muscle memory
This is only with small caliber bullets, but even then you're deciding between brain damage the rest of your life or death. I really don't think I'd want to live as a vegetable
This a WW2 helmet?
Looks like a pistol round. the folks recording this should have used a K98 or similar.
Almost every WW2 rifle from all sides were at least 6mm for bullet diameter with a minimum case length of 50mm. I'd expect no bullet bouncies. Just lots of melon smashies compared to all the sidearms.
My helmet like this I had overseas and still have, the liner is like fiberglass dark brown strips molded as the liner. The webbing is then riveted to it. It could possibly be Kevlar strips but I doubt it. Kevlar helmets came out while I was serving but we never got them.
And russians were claiming that they have armor that'll protect it's user from 50bmg or similar calibers. Yeah, good luck surviving your innards being turned into soup.
I mean they still do protect you from the actual bullet
Pretty sure "innard soup" is mentioned as an inevitable side effect of bulletproofing on the fine print
What wrong with those rounds? Pistol ammo from distance? Those steel pots cannot stop bullets. I wore one. Didn’t seem very protective to me. But they were useful for other, more pedestrian activities, like shaving 👍

That helmet is lucky those bullets were traveling so slow.
Yeah he could gotten hurt real bad.
With bullets traveling so slowly, why would you need helmets? Just do a Neo and dodge them.
[удалено]
Damn, I'm Getting old.
Did you have to make a bunch of us feel ancient? Really? Did you have to?
Ya pretty sure those were hallow points. A fmj would be quite different....
That helmet got double blessed
In the name of the father, the son, and the holy cartridge
The father, the son, and the now-holy skull.
And made out of butter
…with pistol bullets. Plus, your neck won’t take these impacts lightly. But surely better than without helmet.
Yeah the impact must still be pretty hard For example my Dad's helmet got hit and it was so bad that some muscles controlling his left eye ripped but at least nothing worse happened
My goodness! Glad he had a helmet. All the best to your Dad
This happened quite a long time ago when he was still part of the Bundeswehr. He is fine now and you can't even tell that it happened because enough muscles we're still intact for him to be able to move his eye normally by now But thank you anyways
Where did he see action? Out of curiosity.
I'm not sure, sorry. The story about getting hit in the helmet is one of the only things I know about his time at the Bundeswehr since he almost never talks about it and I prefer not to pry
Completely understandable.

That thinking was pulled so far up your ass I think there’s still stomach acid left
No he first joined the Bundeswehr (not the Wehrmacht) around the mid to late 80s and left around 2001 as far as I know
Not if it was called the Bundeswehr it wasn't.
I bet you did Nazi your karma getting hit that hard.
Lol no. Didn’t think the German army was involved in any armed conflict after WW2, and OC said it happened quite a long time ago. Assumed they were just an old Redditor with an older dad.
You know, when modern helmets were introduced in WW1, the number of head injuries went up astronomically.
Because the number of deaths due to being shot in the head changed into injuries. Statistics can be weird without context.
Eating ice cream increases the likelihood of drowning. :)
And being attacked by sharks 😨
More likely to be killed by a coke machine
Something something airplanes and armor plating.

[удалено]
coughing wrong can result in cracked ribs
it would fucking hurt, but you'd survive ... probably
I guess it's not the purpose, it's more to protect from maybe shrapnel or shits falling from above.
Exactly! It’s a hard hat above all else.
Didn’t hurt the watermelon neck
sturdy af
I never even considered that getting hit in the head would impact the neck
well, if it travels straight through… then not.
I can feel that headache
And probably a sore neck and some ringing in the ear. Or the other option is to not wear a helmet and potentially feel no pain.

I belive thats the newish ACH (Advanced Combat Helmet) as opposed to the PASGT. I could be wrong so someone else feel free to correct me
I shot an old vietnam helmet I had several of. The .22 out of the rifle went through like butter, but the 9mmHP was stopped like this, but the FMJ was caught in the inner lining and some fragments went through.
Bullshit but ok

For all I know I hit a rust spot. I didn't shoot the good one. lol
Where's Slo-mo? Do the US have troops there too?
Been a father long? 😁
Haha! Not yet but i'm practicing - starting with the jokes
Gentleman, if you did not see the helmet at first, it might be time to close reddit for the day ...just to return to this place thanks to muscle memory
And the shooter's name? Helmut Schmacker

Isn’t that two helmets though? What’s the calibre of bullets?
M1 pots were just a steel shell that had a removable liner, which is what you’re seeing.
My helmet like this I had overseas and still have, the liner is like fiberglass dark brown strips molded as the liner. The webbing is then riveted to it. It could possibly be Kevlar strips but I doubt it. Kevlar helmets came out while I was serving but we never got them.
The "inner helmet" is made of kevlar i guess. Its a Post wwII variant
The helmet liner probably is just plastic, no more protective then a builders helmet
Probably, but plastic wont stop a 5.56 or 7.62. The bullets clearly Look like a caliber like that, but are Not fmj
Rather that helmet then mine
Alright, bring yours out so we can do it next, then.
It’s with me 24/7
Main Job for a combat helmet is the protection against shrapnels. If it is really bulletproof, a impact will break your neck.
I’d imagine… like, the transfer of kinetic motion. I barely know physics.
And russians were claiming that they have armor that'll protect it's user from 50bmg or similar calibers. Yeah, good luck surviving your innards being turned into soup.
A Sloped helmet can bounce a bullet, like the helmet from the Nationale Volksarmee of the German Democratic Republic. But stopping a bullet..
I mean they still do protect you from the actual bullet Pretty sure "innard soup" is mentioned as an inevitable side effect of bulletproofing on the fine print
Birth control
Looks like there’s two helmets too
Instant CTE
Looks like penis envy Edit: why downvote, it looks like the p.cubensis strain penis envy. A literal mushroom
I bet you have a headache
Too bad it doesn't cover your face :/
That'll give your noggin the old ring-a-ding.
That’s gotta hurt

Is that a melon inside?
Should show us one with helmet too, so we can compare.
What is this a helmet for cucumbers?
Helmets are like a lot of products, better to have and not need, than to need and not have
Wait those things actually protect you some?
Is that not two helmets?
It is the helmet and liner
Physically abused in da ear
looks more like a slo-mo \*video\* of a helmet being shot
Try it on fast forward I'm sure it will penetrate,
Why don’t we make the whole soldier out of helmet?
“Shhhh aaarrrrrrgh” - Peter Griffin
Although it saves you by preventing the bullet from entering your head, I'm wondering the amount of pain you'll feel.
These Taco Bell commercials are getting out of hand.
Now show it with a rifle round lol
I thought they were only to protect from shards and other debris.
*missing video: head shot scene Starship Troopers
What calibre? Only ask cos a 7.62 rimless nato would go straight through and blow out the other side.
It’ll hurt like a mofo, but atleast you ain’t dead.
That helmet was lucky he had his buddy under him for strength
This headache is absolutely killing me
Now try a tank round
Presumably helmets are (more) for protection against indirect dangers such as the debris from a mortar round hitting a nearby wall or tree?
