What exactly is the logic for operators to not wear helmets?
The likelihood of being shot in the head is very small
>>29841060
they are uncomfortable and heavy and don't stop bullets. helmets are there to protect you from fragmentation and bumping your skull on shit.
>>29841072
Head wounds are the largest cause of death during war though.
>>29841060
Helmets don't stop full powered rifle rounds.
>>29841118
Speaks volumes about the effectiveness of helmets, eh?
>>29841118
From bullets? Or shrapnel?
>>29841118
Because of artillery frag. Most SF operators aren't getting shelled.
>>29841095
i remember hearing this about those old WW1 kettle style helmets
is it really still true today? i'd thought the modern helmet was quite well armored
>>29841141
They'll stop pistol bullets, but not rifle rounds. Sometimes, you'll get lucky and it might deflect a ricochet or glancing round
>>29841060
They ooerate over longer ranges with less rest and resupply than a regular infantryman so they prioritize other gear over a helmet.
>>29841121
this
>>29841141
Modern helmets will stop a normal pistol round, but are really meant to stop fragments.
>>29841141
At a far enough range and the right angle it might stop a rifle bullet but they're not really designed to stop bullets.
>>29841141
no they are made of kevlar they only stop very very very low energy rifle rounds. they have stopped AK arounds but only when they like rake the length of the helmet. and when that happens it snaps your head back hard enough to knock you out.
they will stop pistol rounds but you are going to be dazed as fuck and probably not survive a follow up shot. the helmets just aren't designed for that. its meant to protect you brain from leaving your skull when a piece of spinning metal the size of your hand is flying through the air.
>>29841060
platoon sergeant's not screaming to put your fuckin' kevlar back on.

hmm reminds me of a hard hat. like "okay idiots put these on so you don't get brained by a falling brick when you aren't paying attention"
>>29841236
>muh semantics
>>29841222
7.62x39 is a shit round.
he was shot from way outside of the effective range of an AK-47 and it was a glancing hit that raked the side of his head between the layers of material.
>>29841262
that's a lot of conjecture pal
>>29841244
except there are a thousand tiny bricks flying at you at the speed of a shotgun slug.
i thought the slim "operator" helmets were designed for the bullet to ride the curve of the helmet instead of stopping it completely.
>>29841284
there is a video of it happening. and you can see the entry and exit deformations.
>>29841295
all kevlar helmets do that. the bullet goes in and it's flattened and turns to spall and rides between the layers of material.
I've seen two marines survive rifle rounds to the Kevlar, and five helmets catch shrapnel that would've killed them.
They don't wear them because they have the wherewithal to decide when and where they are likely to purposefully be getting into a gunfight.
I think I'd still want to wear a slim profile helmet even if a heavy full-size kevlar helmet wasn't worth it.
Raining debris, heavy shell casings, potentially falling or being knocked unconscious... there are a lot of reasons to protect your head from impacts other than bullets.

they missed him and only hit helmet
also known as "dinked"
>>29841284
look at the exit hole you idiot
>>29841431
I was trying to show that helmets can help. So that wasn't a full on hit? or the dink was just scraping the top where it was shown fucked up?

get out normie
Basically sacrificing minimal protection for comfort and maneuverability. Brain buckets are just uncomfortable and you never wear them for reconnaissance and surveillance.
>>29841060
On a side note, do Crye Precision helmets actually reduce concussive forces on the brain produced by explosions? How do they compare to the standard issue Kevlar?
>>29841456
The dude got very lucky. The round hit at a such a rare angle that it deflected the bullet. That kind of thing rarely ever happens.
>>29841191
> when that happens it snaps your head back hard enough to knock you out.
i want this meme to end
>>29841380
>The major cause of instantaneous death was dismemberment (498 cases), followed by brain injury (489)
I can't find it right now but I read somewhere that around WWI when helmets were becoming standard that head injuries from shrapnel and blunt trauma were the most common cause of death.
>>29841489
Crye helmets have the same ballistic rating as kevlar helmets. They are just adapted and upgraded version of MICH, PASGT and whatnot. They are also a lot more light weight and "slick" than regular buckets. And let's not forget that they are waaaay cooler than issued helmets
>>29841502
Cool, thanks for the info. So had he had a direct hit, say in the front of the helmet where say he would hook up his NVG's, he'd been done or in deep shit?
>>29841380
>The major cause of instantaneous death was dismemberment (498 cases), followed by brain injury (489). Heart and thoracic injury caused 349 mortalities.
>The causes of death among those who died before arriving at a hospital was brain injury (940 cases)
Might want to read your own citation, genius.
>uncontrolled blood loss was the leading cause of death in 90 percent of the potentially survivable battlefield cases
>potentially survivable
>>29841836
Forgot this
>But the study also notes that 90 percent of the deaths occurred before the injured reached a medical facility
Brain injury being the most significant cause of death before arriving at hospital as was said here.
>The causes of death among those who died before arriving at a hospital was brain injury (940 cases)

None of these answer my question as to why you would go without any protection for your head.
>>29842253
weight. sometimes they won't wear plates either.
comfort is also a part of it
>>29842253
helmets and plates are uncomfortable. Most soldier will actually avoid wearing armor if they can get always with it.
it's just people like your SEALS or what not can get away with it more often. If they know they are going into a combat situation they will wear them.
>>29842253
They feel that improved comfort, reduced fatigue, and better situational awareness are worth the loss of head protection.
They're also more likely to be able to dictate the terms of engagements, and less likely to be ambushed or hit by IEDs than typical soldiers on patrol.
>>29842509
what is this pic and why is it in every thread
SF job involves a lot of innawoods shit, and a lot less shootout.
So why a helmet when your goal is to avoid contact and do whatever the shit boss tells you to?
>>29841121
No, but they can protect against a glancing hit.
>>29841060
>vision & hearing reduced by wearing
>also distracting, slow your head movement, fatiguing, sweating in them is terrible, chinstrap sucks, shitty straps, just digs into your skull, makes you tired, literally you will fall asleep if wearing a helmet in the prone position true story
>>29842372
He's 100 percent right
thanks anon
with a small subnote on the possibility of being shelled by isis relatively low. And besides, when you expose your head, your FACE is still very vulnerable, so helmets aren't too helpful in that regard if you are returning fire.
It's a distraction. Gotta keep your head on a swivel, I guess.
>>29841118
During WW1 maybe. That's why they started wearing helmets. Helmets are not to stop bullets or even shrapnel. Helmets are for two things
1) They protect you from falling debris following an explosion. This is why they wore them during WWI. Very few shells actually landed in the trenches, so the bulk of casualties were inflicted by debris kicked up by explosions raining down afterwards. You'll probably notice looking at old war photographs that early helmets were very flat and were worn near the back of the head. They were meant to stop things falling from above, not flying at your face.
2) Not hitting your head on shit. Underrated, but very important. You're going to feel really stupid being medivaced because you scalped yourself on a loose piece of rebar.
If you're not expecting to be shelled or in hazerdous/unstable structures, the benefits of a helmet are extremely limited. Meanwhile, they're heavy as shit and cook your brain, so it's easy to see why someone who isn't going into a pitched infantry battle might not want one.
Why are they called "operators"? Never understood that.
>>29841121
ECH can stop a 7.62x39mm from 25 yards
>>29841060
>>29844296
The old shit that I used doesn't even stop rifle rounds, but I think the new ones will.
You aren't very likely to get hit in the head anyway. Anyone that has worn a kevlar/ACH for an extended period of time knows they are a pain in the ass. They inhibit movement, and are particularly annoying in the prone position. It literally feels like a bucket on your head.
As far as 'super soldiers' are concerned, let them do whatever they want, obviously they get the job done.
>>29844194
The definition has changed over the years. It used to be different. Now everyone that participates in a fun run is an operator.
Realistically it is top tier soldiers, green berets, navy seals etc.
>>29841060
Strap some kevlar on your dome and run around the woods for a couple hours.
You will find that your speed has decreased, with simultaneous increased drag.
>>29842550
Looks like it's an Arma 3 screenshot.
Pretty sexy if you ask me.

Aren't guns in Arma 3 all ugly fake future guns with straight mags and shit?
>>29846664
Mods took care of that. There's plenty of realistic weapon packs out there for Arma 3.
>>29841060
Helmets fuck with your hearing and spatial awareness, they don't stop bullets anyways, etc.
>>29841285
Yeah, because bullets hitting things never cause structural deterioration or chunks of concrete from breaking loose... fucking /sarcasm

>Tora Bora
If you call sitting in a mountainside hide site at 13000 ft above sea level, staring through a SOFLAM and calling JDAMs "direct action" then sure. The vast majority of guys kicking doors are wearing lids, because it doesn't matter how operator you are if you can't remember the way home on long drives because TBI.
>>29841380
hemorrhage is the leading cause of [b]PREVENTABLE[/b] battlefield deaths.
>>29844113
Fallin debris, huh?
While debris can be lethal, it was not the main reason. Helmets protected against shrapnel shells which had an effect similar to firing a giant shotgun at soldiers from above.
