Body Armor WW3

Do an experiment: wear a plate of you choice, go to range, stand at 100 yards line and ask somebody to shoot you with Ar15 as soldiers supposed to do: quick semiauto fire. And by this save us from you stupid posts.

Theres no body armor on earth that will protect you from an AP .50 BMG. And even if by "small arms" you actually meant intermediate cartridges currently utilized by common service rifles I think you'd be surprised what hot rounds out of a 20" barrel can do.

In any case to answer your question it would basically just come down to each side trying to establish air supremacy at which point the battle is over.

I would be completely fine as long as said rounds impacted against my plate. What was your point again?

I think it was that modern warfare occurs on shooting ranges, with riflemen unloading their magazines at unobstructed targets 25 yards away. I could be wrong about that one though.

His point, you insufferable fucking retard, is that plates only cover a very small part of your body. Bullets and shrapnel can still hit your entire abdomen, your sides, your neck, your back, your head and your limbs.
Even in the case where body armor started becoming an issue, governments could very quickly fund the mass-production and issue of armor-piercing rounds.

It is

Weight. Cost.

Are soldiers trained to aim at the limbs, abdomen, head, or are they trained to aim at center mass.

No it isn't

They just shoot at the general direction and hope for the best. There's a lot more exposed areas than the plate can cover.

LOL. Yeah, that's why the SOF mantra against enemies with armour is "hips and heads".
I'd laugh my ass off to see you bleeding out from a groin shot, or massive shrapnel damage to your arms and legs.

Soldiers (and by this I assume you to mean non-specialised or non-combat troops) are trained to fire until their target drops. Natural dispersion from multi-shot firing would disperse rounds to hit your hip area, arms, and unarmoured parts such as your armpits.
Armour will stop a couple of shots but if you really think you'll get away without injury, do try to remember that the energy of a round striking a plate can still crack a rib.
No matter what, you'll be out of action, even before someone drops a grenade into your hole to finish you off.

I thought the northern hemisphere summer was over by now?

Ever since 2007 we've been in a state of eternal summer. The only solution is to remove internet access from all mobile devices.

My point is: just do it, buddy. And post video.

They are. But real world accuracy of small arms fire is so low that bullet hits recorded in post combat BDA studies are all randomly dispersed across presented body projection (head and neck have some disproportion and get more hits then their presented area, obviously cos they are exposed to teh fire the most, too bad beloved rifle plates are no help here). Rifle plates cover 15% of frontal standing body area. Now do the math (inb4 prone, in prone they cover 0%).

Modern armor isn't invulnerable. US has good luck in the Middle East because the snackbars mainly use 7.62x39. Russians are issuing 5.45x39 which, like 5.56, is an absolute armor killer. Add to this that the US relies in ceramic plates which are only good for a few rounds and now the reason for issuing everyone fully-automatic weapons is apparent. Dump 10 rounds of a small, fast cartridge into a level IV ceramic plate and you're likely to get penetration even though it's "rated" to stop larger calibers.

It excites me that artillery has shown itself to be useful again, but it also disappoints me in that the United States has significantly decreased our use of artillery in doctrine because the big whigs deemed it useless in the jet age.

The guys that are outfitted with thermobaric weapons come with heavy armor that will allow them to use explosives in close combat without fear of shrapnel.

Level III flak vest for regular infantry + collar and neck flap on helmets (space helmets + beakies are the future).

Close combat units however should wear A LOT more armor than regular units if you don't want to level a city bloc with artillery every time you need to take one.

Why not use chemicals instead? Muh warcrimes is not an argument

Getting hit with a 5.45 and a 5.56 are a whole nother category in comparison to bigger shit like .30-06, .303 and the like.

By shooting each other's dicks.

You have no armor there, and even if you miss, chances are that you are going to hit an artery, or bone, or more or less the weakest part of the armor that the target is carrying.

Just use thermobarics. Your enemy will not fight you if he has no oxygen. Or functioning lungs for that matter.

That armor is meaningless when you get killed by the over pressure from the thermobaric.

lol

Of course. But thermobaric ammo aren't just vacuum explosions, they also make bigger explosions which means more shit flying at high speed.
The russian data roughly equals 1 RPO rocket to a 155mm HE shell so basically a RPO sapper team is always technically in the kill radius of the weapon (which is why that shit isn't mass issued, you do need the sapper special course "the 1001 to blow yourself up and how not do it".)

I'm waiting for companies to start making polyethylene breast plates, not just tiny rifle plates. They're light enough you could cover a large area for the same weight as a ceramic lvl4 plate. The plastic ones are only lvl3, but I'd take more coverage over more concentrated protection. Hell you could make full plate armor out of the stuff for breaching teams.

Yeah, UHMWPE is the shit.

UHMWPE Lorica Segmentata when?

RPO has effective casualty radius of 5 m.

I thought about same thing. Also you can combine level 3 and level 4 in same suit. Make breastplate of UHMWPE at level 3 and then reinforce plate area with ceramics to the level 4. (BTW Rifle plates are same design already, ceramic layer over UHMWPE backing and antispall UHMWPE/kevlar coverage on top). So you have both existing level 4 coverage and all around level 3 coverage.

Animated armors would not work with level 3 UHMWPE, its too thick at ~30mm, when steel was just 1.5mm

UHMWPE

Pros

Cons

Forgot this in my last post but you guys are forgetting about aerogel.

Injection moldiding it would remove the need to machine it, or 3d print it.
The high thermal expansion coefficient might make it hard to do composites it.
Just thinking about AR500 style plates with UHMWPE addition to save on the thickness of steel needed, with additional bonus of the fragmentation being dealt with.

I wonder if we will see face masks with built-in gas masks. With all the dust and WP it will be a godsend.

Sounds like it's not a concern for something like the GM-94 though.

How would a "hauberk" made of it function?
That sounds excellent.

That was not the point of the breastplates. The point was that melee combat still happened, with swords, halberds, and bayonets.

So is that Ronin bulletproof helmet thing the real deal or not?

In the Marines we are taught to shoot chest, pelvis and head. However in an actual fire fight I would be just shooting in the general direction fire is coming from and if I can actually see them through my optic then I would still be just trying to shoot them anywhere(prioritizing chest obv since its the largest target) you're not really going to be sitting there like you do in a video game lining up the perfect head-shot because if you can see them, they can see you and your life is at risk so you just shoot them and training takes over. Note: I have no combat experience i'm just making assumptions here.

Actually user as someone in the military I can tell you in terms of the south China sea at least artillery will play a bigger role then you think.

it will turn into 7 foot tall supersoldiers stalking through underground tunnels in rubble to shoot each other with 80 caliber APIE ammo from oversized FALs and SVDs.

You play too much Fallout.

dudes who get shot in the arms or legs will be out of commission real fast
dudes who get shot in the head will be dead
dudes who get shot in the bulletproof area will be dead after 3, 4, 5+ shots instead of 1 (though each shot will knock them down and put them in progressively worse pain)
grenades and explosives and tanks will still exist
snipers will still be able to target unarmored areas
armor-piercing ammo still exists

So yeah, it'll take longer to kill people for both sides, but it's not like they're going to throw up their arms and say "fuck it, we can't kill each other; let's all go home"

also remember that the goal of any war is not "kill as many people as possible - whoever kills the most wins"

casualties =/= deaths
war is just a byproduct of politics… just a more intense version of negotiating

You're on the money with every other point AFAIK but I'm pretty sure UHMWPE can't be injection molded, at least if it's to be used for armor. The armor gets a large portion of its strength from alternating the angle of the fibers across multiple layers and I don't know of a way you can create any sort of cohesively oriented fiber structure through an injection molding process.

That's the lethal radius of the original RPO which had some kind of napalm in it.
We're talking about thermobaric RPO (A series) of course.
After looking it up it's not a 155mm but a demolition effect similar to a 122mm shell blast and a lethal radius of 50m in an open area (and 80m^3 in an enclosed area).
Knowing the warhead is 2.1kg of a thermobaric compound when a classic WARPACT 122mm shell is 3.6kg of TNT it's doesn't appear to be a ludicrous claim that the effects are similar given how better thermobaric compound are.
And the newest RPO (RPO PDM) have a 3kg payload.

Of course the downside of a heavy payload on relatively small rockets is the range… hence the armor and the sapper formation as it is a weapon system that will definitely kill it's operator if fucked with.

oh user tell that to the ghosts of the millions who have died in world wars.

Can someone clue me in as to why titanium isn't being talked about?

It's rare and hard-to-work-with, and that makes it expensive, therefore it's out of the question for mass-issued items. Also, it's not a Wundermaterial, it's just halfway between steel and aluminium both in strenght and weight. It's only good when aluminium is too weak for a certain application but you want to save weight. Also, South Koreans experimented with steel-aluminium alloys that have similar strenght to titanium while being even lighter. Once the technology is fully developed titanium will be only used in certain fields (like medicine).

Straight from the horse's mouth. Soviet RPO-A field manual. Killing area in the open is 50m2. Now do the math.

Things is people mix up fragmentation lethality effects and blast effects (and PRO has plastics shell and no fragmentation effects). Numbers are quoted for arty shells are fragmentation effects and and they outrange blast by many times. Blast effects have much much less range than people think.
