Ok seeing as i'm no expert in anything military related i thought i'd post a few questions to see if this idea of mine for a fabricated neuropsych case study is slightly possible. Please bare with me if these are really stupid questions!

Can a bullet penetrate ADF issued helmets? I presumed so.

What is the degree of protection a helmet provides? ie can a bullet fragment enter and possibly pass through to the skull or can a bullet fragment on impact with pieces passing through?

Oh and don't take this too seriously, its a very small part of the case study!!

Thanks!

Xaboo

too many variables...

 

i.e;

What is the degree of protection a helmet provides? ie can a bullet fragment enter and possibly pass through to the skull

what size fragment? how close to the detonation? what type of round?

 

how about you give a scenario?

What type of weapon is firing the round? ect ect

Also need to consider what material is used for the helmet, good luck trying to find specifics on that one as well.

I've posted this before, but I'll post it again:

http://www.defence.gov.au/news/armynews/editions/1097/topstories/story01.htM

 

The key differences:

1. PAS-GT (Current)

2. ECH (New - not in service)

 

Protection against fragmentation

1. 620m/s

2. 650m/s

 

Helmet shell integrity against low speed impact

1. Not specified

2. Yes

 

Protection from small arms projectiles

1. Not specified

2. Yes – Type IIIA (44 magnum and 9mm Full Metal Jacket

 

Weight – Medium

1. 1.5kg

2. 1.25kg

 

Weight – Large

1. 1.62kg

2. 1.3kg

Funny thing is i don't need specifics, it just needs to sound plausible and i was wondering whether its remotely possible!

 

Lets say it was fired from an Ak-47 (or similar insurgent weapon) with a distance of around 300m.

Helmet really depends on whatever is used for soldiers these days ie MICH TC-200 COmbat helmet or the light weight helmet.

 

What i'm trying to do is to create an incident in which some lesions in the dorsolateral and mediofrontal prefrontal cortices occur. So my idea was to have small fragments to enter the head and lodge in the brain but without causing enough damage to kill.

Anything that involves balistics is possible, but it all depends on how seriously you want to be taken I guess.

 

Hell, a dude's tooth stopped a bullet going through his head in Iraq.

 

As was said above, there's way too many variables:

What was the nationality of the soldier, as each Army uses different helmets.

Given the nationality of the soldier, what was the test-grade of the helmet? Was it rated to stop a 5.56mm round at x meters?

Did the bullet richochet off of the ground or another surface? (thus losing velocity)

What was the angle of the shot?

What was the calibre of the round?

What was the muzzle velocity of the round as it was shot from the weapon?

 

You might be better off looking at schrapnel wounds.

Then thats all I need. This was more to satisfy my own curiosity as to whether my idea was based on something impossible.

 

Oh and this is for you McDeth:

Question: Is it possible.

 

Answer: Yes.

 

Man you guys really missed the point of his question, lol.

i thought the ADF was using the american MICH now

 

that ECH looks exactly like it too

get your hands on a helmet and shoot it with different firearms from say 50 yards

I reckon make a helmet out of Ipods. Supposedly one saved a diggers life.

Save ya life, abuse an apple product!

^^ stranger things have happend.

A British soldier in Afghanistan was dubbed the luckiest man in the military on Monday after a Taliban bullet pierced his helmet - and he lived to tell the tale...

Negative, it's made by Rabintex which is an Israeli company.

 

The MICH was developed by USA SSC-Natick.

Interesting and related (head injuries/bullet/brain).

http://en.wikipedia.org/wiki/Robert_Lawrence_(British_Army)

Robert Alasdair Davidson Lawrence MC (born July 3rd 1960) is a former British Army

officer who fought and was severely wounded in the Falklands War.

 

Lawrence wrote about his experience in the Scots Guards at the Battle of Mount Tumbledown

and the injury he sustained at the hands of an Argentine sniper. A 7.62x51 mm round passed

through the rear of his skull, emerging at his hairline above his right eye. Lawrence lay on the

thin cover of snow on the exposed mountaintop for six hours as colleagues pushed his brains

inside his broken head. Airlifted off Tumbledown, Lawrence was left outside a makeshift operating

theatre with no painkillers. Two days from his 22nd birthday, he assumed he was the last to be

operated on because he was the least likely to survive.

 

Lawrence lost 43% of his brain and was paralysed down one side of his body. He was awarded

the Military Cross. His book was adapted into the BBC television programme Tumbledown, starring

Colin Firth as Lawrence, which was viewed by more than 10 million people on its first showing.

After leaving the army as a Captain, Lawrence married and emigrated to Australia where he worked

in the film industry. He subsequently got divorced and returned to England. He has re-married. He

was interviewed by several British newspapers on the 25th anniversary of the Falklands War.

I heard about this on the TV years ago.

Wow thats both interested and amazing. 43% is a lot of mass to lose so i'm interested to see what other symptoms he has aside from being paralysed on the one side. The bullet must've knocked out a lot of association cortex (non life supporting areas). I reckon a bit lower down at the rear and it would've gone through his brainstem which means game over.

theres also the soldier who went around a corner and got shot in the mouth from a guy standing there with a pistol dunno where i seen it.. ahh found a different site same story http://www.snopes.com/photos/military/teeth.asp

Wow that tooth one is awesome. What a legend

why did he have his mouth open enough that his teeth were showing ?

 

 

 

As you can see from the pics it didn't blow his lips off or anything

theres a hole above his lip by his nose

Could had also separated his neo-cortex which would had made his life even more interesting. There are plenty of cases of people being shot/nailed/fragmented/machine gun springed in the head and lived to talk about it. I do believe one of the more interesting I have ever heard of was when a car manufacturer worker was installing airbags, one of the ballistic "shells" detonated in the pack which then shot more of them into his skull. Not only was it fun for the surgeon getting them out since they were still considered volatile, since it could had ruptured and blew the other part of his brain up and all. But imagine having a mini grenade shot into your head!

Be one hell of a scar to show off thats for sure.

 

"yea i got shot in the face, look"
