Snipers suffer irreversible brain damage from 'invisible shock waves'

Aussie veterans who helped train Iraqi snipers say they were exposed to hundreds of blasts a day, leaving them with long-term brain injuries.

It's crazy to think there's so much evidence around OP and the negative effects and we are STILL not using suppressors broadly in Aus.

I did years as an instructor in Defence, then went into other spaces with SBRs and bolt guns unsuppressed. The tempo resulted in continual exposure to the point we started developing concussion sickness.

I remember some days on the rapid fire drills and volleys where the concussion and reverb off the steel roof and walls would rattle my head so much that my vision would blur and i'd have pain through my sinus.

It's been a couple of years but i'm now starting to really see the symptoms show up. I'll forget what i'm talking about mid sentence, i'll forget words. It's scary. It's like my brain just.... stops thinking. And that's just now. I'm not even 40. What happens when I'm 60?

The thing that is outrageous is that these studies and reports are done every few years. Same findings every time. Nothing changes.

Wedgetail is one of Defence T&E groups, makes some of the best suppressors in the world, and got the contract for the next gen infantry weapon (and are good blokes). Suppressors could be a locally sourced, commercially available solution, that is recommended in every single one of these reports. And Defence (and other agencies for that matter) won't do fuck all about it because of the perception of suppressors.

It's more publicly acceptable to have diggers with brain damage and to pay out millions of dollars from DVA, than it is to be seen with a suppressed rifle.

I'm not triggered and immediately rolling my eye's because I was an Artillerymen..... but, I mean... I kind of am. Gun crews have to rotate out something like every 160 rounds of 155mm... I wasn't a gun bunny I was on the computation side of things, still been in the field when training near them and yeah, they got some blast to them.


Also myself and plenty of other veterans I can't help but see stuff like this and think of all the IED's that went off hitting our vehicles or directly in front of or behind us and want to roll there eyes... Problem is, over pressure is just a problem, period so I'm actively having to try not to be annoyed at the idea of someone complaining about it from just something like a large bore rifle with a brake. Because it probably is a thing as well, if you're doing lots of shooting every day, day in and out next to or behind them...just to a lesser degree spread out over longer but maybe just as damaging.

That's a big part of why I don't have much interest in shooting .50s anymore, and why I suppress everything I can, especially SBRs.

If you want to think your method of getting a brain injury makes your brain injury more prestigious or whatever the competition is, then I say GO FOR IT! Be the most brain damaged man you can be!

l honestly feel like there just isn't ENOUGH competition in the TBI community.

Lets see if we can get a bit of a Crips vs Bloods thing going. Dudes who's TBI was cumulative, vs dudes who's TBI was incidental.

We form ranks on opposing sides of a field and when the whistle blows, if we can remember why we were there, we then bum rush each other and try to finish the job our respective mechanisms of injury started. Winner is who can most coherently drool on themselves afterwards.

The significance of the studies at the small arms level is that it indicates just how big of a problem OP is. There is NO safe level of over-pressure. It is known that OP is a greater concern for artillery and mortar, and those who have been caught in explosions.

Now the studies are concluding that actually, all the way down to the 556, blast is causing brain injury. Like hearing damage, it is suggested that it can be cumulative.

It's known. It's widely reported. The solution is a credit card swipe away. Yet we suppress nothing but the information around it.

I’m laughing because it’s true. I know and knew how it sounded typing it up but still felt like just being honest and divulging , you’re not wrong it’s stupid, your comment was funny and I can laugh at myself.

Does help make for a stronger argument for whisper pickles being deregulated.

lol whisper pickles!?

Probably a good thing we don't make a competition of it....

Commentator:
OH ANOTHER EXCITING DAY HERE AT THE TBI GAMES.
The cumulative team just scored a point, but the scorer has lost count and the score board has just been updated to have LESS points than they had before.

Unfortunately, no one can remember what the score was.... so officials went to the referees to get the actual score only to find the secondary ref has been spotted in his car speeding the wrong way on the freeway to pick his kids up from school, made all the more inconvenient by the fact both his kids are now in their 30s now.

Officials are going to have to call a time out whilst they address the point, as it turns out, the cumulative teams quarter back forgot what team he was on and scored a touch down in his own end zone and has started fighting his own team mates.

Unfortunately it does look like the game is going to be forfeited as the officials discussion has now turned to whether straight spaghetti or spiral spaghetti is better in bolognaise and even though the game is in it's 3rd quarter, the spectators are starting to riot, wondering when the game is going to start.

This is not what you want to see at a memorial game for the inventor of the TBI games who, sadly, passed away by dehydration after forgetting what cupboard in the kitchen the glasses are in.

Thanks for tuning in to the TBI games, I'm.... uh....... uh...... What are YOU looking at!? I'LL KILL YOUR MOTHER!!!! *Strangles Boom Mic Operator*

Not at all surprising.

Doesn’t matter if you’re banging your head against the wall or if loud noises are jarring your brain.

If you get a headache doing something, that means stop.
