- I've made videos talking about and busting tank myths in the past, but there wasn't an overall theme. I decided to switch things up for this video by talking about tank ammunition. Seems like a very particular subject, but you would be surprised by how many misconceptions there are about ammo.

why does your sponsor pc say it can run world of tanks at any res....
damn you ruined my favorite death animation from Red Alert 2 of infantry melting into green goo.
The way you worded the DU rounds about cancer and heavy metals seems a bit shallow. Easy to misunderstand.
Yes no one is denying that breathing heavy metals is bad… but. It wasnt the tankers firing them that had this damage done to them. It was infantry or enemy crews.
The myth is that DU is radioactive, therefore shooting the round gives all tank crews get cancer.
Fun fact: I would prefer not to get hit by any of these tank shells
You're alone on that one, I can't wait to be penetrated by some nice tank shells/s
@@alexandertoucan4956 in which way

In most cases it's not that bad especially direct hint. You wont notice it. Much worse to bleed to death from random shrapnel...
Why not?
Spookston: "overpressure turns driver into a gummy bear"
TV producers: literally turn driver into a cartoon bear
Another widely circulated myth is that HEAT warheads work by melting the Copper lining and making it ''melt'' through the armour.
In reality the pressure from the explosive charge changes the Copper lining into a Superplastic, which is when the pressure causes the otherwise Solid Copper to act more like a stream of fluid, even though it is way below it's melting point and still a Solid. This is important because actual molten metal would just splatter over the armour and not achieve much, but a Superplastic will bore through the armour, since it retains it's Solid form Density.
He went over that in a previous video
Not entirely accurate. The copper liner is well above its melting point but the pressure keeps it super critical. But that isn't the mechanism that makes shaped charge work, the high explosive accelerates the liner to a very high velocity, which gives this mass tremendous kinetic energy. Even if it were vapor, it would still carry this energy into the target.
@@obsidianjane4413 To be even more accurate ; it's the focalization of the annular shock wave created by the explosive that give that kinetic energy to the metallic liner (not always copper tho)
Shaped charge are the most effective transfer of chemical to kinetic energy ! It's all about the accuracy of the focalization of that shock wave
And as anyone know.. increasing pressure mean increase of temperature (well beyond melting point of copper) but puts it in a state of superplasticity which it can hold some mechanical characteristics such as heat conduction..
Slicing create heat and heat can help slicing by reducing mechanical properties, in a HEAT, you got both in a very confined point ! Very efficient way to slice ! (more like punching but it's slicing more than punching away)
@@Real_Claudy_Focan NEEEEEEEEEEEEEEEEEEEEEEEEEEEEEERRRRRRRRD
Just kidding. Physics and mechanics like this just always fly straight over my head.
I would'nt say it's solid , it's still flexible . Shell rotation lowers the penetration of HEAT , cause the centrifugal force pulls this "Superplastic" or copper beam to the outside . This is why only at weapons like a Panzerfaust that does'nt rotate the shell , they got massiv penetration power . Panzerfaust 150 (range 150m) , 100mm diameter and up to 300mm RHA pen . As fin stabilization comes up with tank rounds , HEAT-FS was the new meta .
The tank crewman was most likely inferring that a combination of pressure, speed, and a little bit of heat vaporizes soft targets (i.e. humans or animals). The company that made the animation and hosted the interview most certainly misinterpreted it, and thought the hot spall created causes this "vaporization," which is extremely misleading.
mmmh yes maybe but even if there was 200bar of pressure and 3000 degres(celsus) a human body does not "evaporate", it woulnd be great to see but...
Eh, I often mark shit like that in the "producer said do it again but with more explosions" category, especially on later history channel funded projects. Well, either that or the round teleports aliens into the tank and the crew are death rayed!!! /sarcasm
Human doesn't vaporized, period.
@@jintsuubest9331 You can.. but you have to really stand near an atomic explosion "ground zero" :D
@@jintsuubest9331 Humans can vaporize. Go and ask the people that stood near the nagasaki and hiroshima nukes...Oh wait....
Another good one : HEAT shells " melt " through the armor. The metal jet is " molten ". Its not. It's super plastic, IE behaving like liquid but is in fact solid and the penetration of the jet is still kinetic in nature, it doesnt use high temperatures.
increase of pressure do increase heat, it's physics ! Temp is what slice the armor, it's the pressure, but the resulting heat of that pressure increase helps..
@@Real_Claudy_Focan You have no clue what you are talking about here. Neither about physics or tank shells.
@@Real_Claudy_Focan no lol
the pressure is so high that it basically does melt though
It’s the Monroe effect.
The copper “jet” takes the path of least resistance, which is through the armor, as it doesn’t have the any energy to fight against the pressure from the HE filler.
I should also expand that this essentially works the same as a sabot round, but rather then the kinetic penetrator traveling at supersonic speeds from the muzzle of the tank, it travels at super sonic speeds for that short distance once the fuze arms. This is why a lot of HEAT rounds have a specific stand-off distance, to give the penetrator time to from properly.
I like just remind everyone that according to Gaijin a 1940s german tank crew could take french 47mm to the chest and just turn yellow. Despite historical records showing it was very effective against its target at the time.
just taking a single 50. to the chest should be enough, let alone a 47mm
@@dlyonthescreen2657 Not in Gaijinland,where human tissue is equivalent to 11mm of armor steel.
nigel could take a 12.7mm in the head and only turn yellow
I remember when they introduced the t-44-100. Ivan could easily stop the 128mm with his teeth and swallow the round and i could kill 1 maximum 2 crew.
Yep, B1s never oneshotting
I'm glad you were fair to the tanker in the interview, The documentary film makers clearly were the ones who misinterpreted his meaning too literally
Emm... Tanker in general are master at operating their equipment, but they tend to not know what's going on, but it is not entirely their fault.
Mind you, for the longest time, US army official training material heat shape charge melt throught armor, or at least that's how they are being explained to.
It is simple, grunts job are killing bad guys at the other side. They only have to know AP is for punchy punchy at enemy tank and this thing goes boom is for everything else. They don't need to know unnecessary details.
@@jintsuubest9331 Yep, most soldiers are practically kids after all. Outside of pilots, a high level of technical understanding is not exactly necessary, just practical experience.

Depleted uranium is incredibly dense, almost as dense as most of the defence department
Nah, defense department are denser than neutron star.
Oof lol
I can speak from experience about inhaling the air around heavy metal. I was exposed to the air at an Iron Maiden concert and I've never been quite the same since.
I always find it funny when people hear uranium they think radioactive, which is fair to people who don’t know about it. Depleted uranium comes from the nuclear fuel enrichment process, and in the process of depletion, they are separating the U235 from U238. The U235 goes into the fuel because it’s more fissile, and the U238 is the depleted uranium. For reference, brand new unirradiated Nuclear fuel is safe to touch, so not super radioactive. Depleted uranium is less radioactive than brand new fuel.
The main problem with DU is that is still chemically toxic due to being a heavy metal.
🤓
@@Cowboycomando54 Yes and they found out that tungsten ammo has similar penetration.
Safe to touch because the alpha can't penetrate your skin. Very not safe to ingest because it can penetrate cell membranes and cause damage to DNA and create cancers. Besides its basic heavy metal toxicity.
There's nothing at all funny about it.
It's still radioactive. Less radioactive doesn't mean not radioactive. It's also highly toxic and the dust created from the firing and impact of DU rounds can very easily enter the human body.

While I'm sure the increased post-penetration performance is useful, I'm fairly sure the main reason for the adoption of depleted uranium is the increased penetration.
It's twofold:
1) It's very good at dealing with armor composites.
2) It's cheap, plentiful and readily available as a byproduct of enrichment.
It's two birds with one stone.
@@The_Crimson_Fucker and you dont need to worry about storing radioactive waste

2:22 Understood, APHE creates a minature nuclear explosion. :)
Another misconception I've seen, specifically relating to the arcadey nature of War Thunder, is that APHE is incapable of over pressure. Any round with an explosive filler is capable of over pressure, though usually only HE, HEAT, and HESH have enough to do it. Very high quantities of explosive filler on the larger German and Soviet guns can sometimes trigger a crew wipe.
A perfect example of this would be the KV2 APHE. 5kg of TNT surely will be enough to overpressure.
I see these people have never be shot by an IS-2
Spookston, just wanted to say you’re the best. I don’t know a lot about military technology or tanks, but I have an account on NationStates that I love writing military stuff for. Your videos have given me a lot of help designing my nation’s main battle tank! I really appreciate your content.
Self sharpening DU might also be a myth, the only research i've found on the topic simply describes DU as being less ductile. Which means it forms a smaller mushroom head at the tip when penetrating and thus acts like a smaller diameter penetrator than an equal diameter of WHA.
adiabatic shear banding
For APHE, do you know how much of an influence is the shell's explosive type and amount in play? Surely a KV2 APHE would do more damage than if it were just a solid AP slug of metal? Also, wouldn't the explosion cause massive pressure inside of the crew compartment?
KV2 aphe are not really aphe but a type of anti-concrete round, more of a semi armor piercing HE, but im pretty sure it will explode inside a tank like wt because mmmmh fucking 5kg of tnt
Yes, an APHE round with a huge quantity of explosive filler would definitely cause overpressure effects inside the tank.
KV-2 APHE has about 5kg of TNT, which is way more than enough to reliably kill everyone inside.
When Spookston was talking about APHE, he mainly meant that rounds such as the American M61 or Soviet BR-350A, which usually oneshot nearly any tank from the side in War Thunder, would have very similar damage to solid shot fired from the same guns.
@@fireshredder24 yes I specifically talk about kv2 immense aphe thx
APHE is made to "crack" armor, see it like a good "stunning" round while AP is made to "tear" armor
Don't forget that "tank kill" IRL isnt that spectacular explosion you see in WT ! Sometimes a good crack in the armor without penetration can disable a tank while a round passing through won't do much..
Old APHE were originally made as "anti-fortification" rounds or AA rounds to spread shrapnel, the effect researched in both cases is concussion rather than penetration
@@Real_Claudy_Focan
Try again. AP in general are meant to get throught armor and do shit inside of armor.
Shoutout to spooks for having one of the least obnoxious ad reads I've heard in a while!
what about the myth that tank ammo explodes when shot, instead of simply vanishing onto the aether? or the polar opposite, the shell changes colour slightly, and it doesnt like this very much, so it has a temper tantrum and murders the crew members?
Any chance you'll make a new future tank technology video? Or more redesigns of fictional vehicles?
Honestly, probably not. Spook got a lot of flak for many fictional vehicles because he didnt criticize the vehicle using the rules of the fictional universe. His talk about Planetside 2 vehicles exemplify that. His best forte is real vehicles.
@@TheClone37 Yeah but real vehicles isn't why i subbed to this channel, i don't watch 90% of what he posts now.

Very interesting topic, keep up the good work. :)
3:15 as a die hard Metalhead,I can't agree with you about this one
The self-sharpening effect of sabots comes from the way they are made, not the material used.
Me: fires Uranium shell
My loader: don't you mean depleted Uranium.
You loaded depleted Uranium shell right?
The nuke I just loaded: Kaboom
Another thing is APHE pens worse, since you’ve hollowed out the round a bit to put high explosive in it

Im glad you mentioned it, the radioactivity of DU is a total non-issue. People scared to death of tank husks because of radioactivity forget that those rounds were stored in an Abrams all at once, with the high energy Gamma completely ignoring things like even the armored ammo locker door. If it was as dangerous as they act, the crew of every Abrams would be dead in a few hours after entering the tank. But it's absolutely right too, that Uranium is poisonous, and that's actually dangerous. Basically like lead poisoning, so still stay out of tank husks so you dont breathe that crap in.
And too the idea that DU was increasing the rate of cancer in children in the Middle-East is one of the most boneheaded things Ive ever heard. Firstly the only time we truly know radioactivity actually causes cancer is in the cases where you receive life-threatening doses of radiation, like nearly dying from Iodine-131 and later getting leukemia or thyroid cancer. Secondly there's not nearly enough being spread over the countries to actually increase background radiation to dangerous levels. You might as well say tank exhaust is giving kids carbon monoxide poisoning, or the lead from bullets is giving them lead poisoning, or the smell of military portapotties are giving middle-eastern kids nausea.
So why are the statistics saying that? Probably because we didn't properly measure and diagnose cancer in the Middle-East before. So of course it looks like the rates are going up.
Hello spook ! Just to tell you that you are awesome, keep up the good work !
Sorry spook but I cannot concentrste when you drop that bombass gameplay bro. You're a beast
I saw a comments section arguing about if a high calibre hesh shell would be sufficiently broken up by cage armour to not critically damage a lightly armoured tank. People were claiming the the sheer mass and explosive force or a shell like the one carried by the FV4005 would make it relatively unaffected by cages on tanks. I feel like this is untrue but could be something to look into for a part 2. nice video.
Very good video
Actually DU- APDSFS rod penetrator rounds are capped too, and not sharp/pointy but rather blunt, like most AP tank ammo. We had one fall about 6-8 feet point first onto concrete, and the tip bent. Most diagrams show a pointy tip, but on occasion you can find an accurate diagram , which shows the wind-screen/cap.
Spookston, my father was a Ranger operating in both Bosnia and the Gulf War. On a few occasions he has talked to me about inspecting knocked out T-72s and other enemy armor. The crews on occasion were indeed “melted.” To such an extent that the only remains he could find in fighting compartment were some knuckles of the spine.
Well, cremated would probably be the better term. Nothing really special though. I mean a tank is nothing else than a metall box you're sitting in with a lot of burny stuff all around you. When the ammo after a hit deflagrades it's like you're in a oven of a crematorium. Appart from some bones, nothing will be left.
@@shi01 that’s exactly right
I don't understand a word but it's entertaining and I like spook's voice
APHE performance varies greatly depending on factors such as type of fuse, type of explosive(even taking TNT equivalent the speed of the blast being different the effect can vary quite a lot), shell speed, fuse time etc.
the worst APHE are about equal to an simple solid shot
That moment when a video trying to bust myths itself spreads myths.
How so?
@@KP3droflxp Uranium being "self-sharpening" (it isn't, other people in the comments go into more detail on what it actually does when it hits a target, but it isn't "self-sharpening")
APHE being useless (it wasn't, he's relying on old British firing tests using 50mm or smaller guns, further demonstrated by the fact that British battleship shells DO have explosive filler and it IS more effective, and you would think that the forces in play there would be much greater than those involved with 75mm APHE shell; basically said firing tests were not scaled up to to larger calibers and were meant to justify the British continuing to use solid AP, which they ended up doing in the early war). Sure, the shrapnel may or may not end up forming a cone similar to an AP shell, but the real damage is done by the overpressure of the HE element, not the shrapnel, in an APHE.
I think the liquefaction story come from another story from tests on the Bradley IFV. How the story goes, is that they took a broadside shot at a Bradley that had a couple of goats or sheep inside, to test weapon effects. When the vehicle was checked after the APFSDS shot, there was a clean set of entry & exit holes, & a fan of viscera on the ground of the exit side. Supposedly, the high speed shockwave of the round passing through first liquefied the livestock, then created a vacuum effect on exit. This supposedly pulled the liquefied remains out of the Bradley & deposited it in a fan shape on the ground downrange. I first heard this in the '90s & have shared the story, myself. However, I have been unable to verify it's accuracy.
i like how friction was completely thrown over board in this video.
Thanks for the video I always felt that the explanation for a capped shell was odd as it's not like the angular momentum would just disappear.
4:47 lol every time you say "anyway" it sounds like you're rolling your eyes and you're just glad that the video is over and you can go back to doing whatever
love these viedos
here in the UK, my father had some depleted uranium masonry drill bits, back in the 1980's. They had a health warning to wash hands, thoroughly, after handling, especially before eating.
Should also wear an anti-dust mask for the reason Spookston described. No need to end life too early because of inhaling the DU particles.
The US Army Officer talking is an actual personal friend and is a big name in the US Armor world when it comes to tanks.
When SABOT rounds strike yes, they have thr ability to liquefy tissue cause what happens is the crew is stucked out the hole that the SABOT round creates upon exiting the target. Yes, not all of the liquefied matter is taken out, hence leaving behind different tissue of a human body that is in semi liquid forum, which yes can quite litterly hosed out of a tank.
It is also a myth that DU is self sharpening. It is just not mushrooming as much as Tungsten and therefore leaving a smaller hole while penetrating deeper. I'm early tests and do it's structure the scientists believed that it was due to layers peeling of but that has been proven to be incorrect many years later. However this myth is still around and widely spread among literature.
I love these
Love the daily tip
I enjoyed the video
One thing that should have been mentioned is that while APCR does have a higher ability to bounce, it doesn’t mean it won’t go though angled armor. It works just like apds just more primitive
Fun fact: I got a "Shell Shattered" effect 3 days ago when playing warthunder and failing to pen a tank.
Hello Spookston have you ever done a video covering the German CL-13s? I wondered what your opinion was on CL-13s being matched up against Phantoms and MiG-21s
Great video, those myths are so prevalent. One I think you could have added is the HEAT myth that the shaped charge liquifies the copper liner before it's sent through the armour. From my reading on the subject, the shaped charge merely accelerates a smaller penetrator inside the HEAT round, adding energy to an already fast moving object, thus increasing the penetration. Liquid copper would have no effect on armour, at all, no matter how fast it's moving; it'd just solidify on the outside as steel requires a good 300°C-500°C more than copper to melt.
This applies to tank HEAT shells, RPGs, etc.
I think the distinctions between molten and not molten are fairly academic at ballistic velocities. The copper is probably "molten" insofar as it behaves more like a liquid than a solid and is probably quite hot, but the actual mechanism of penetration is more to do with velocity and concentration of force. The jet of copper is very dense and moving extremely quickly, and is able to displace and deform the steel in it's path.
High enough pressure GAS could penetrate armor.... It's essentially a liquid but because it's under so much pressure it's density is such that it technically counts as a solid. - Despite flowing like a liquid and being extremely hot..
@@OGPatriot03 A gas at a pressure where it has the density of a solif is considered a solid due to it being solid.
I love your videos man. Is there a chance for you to enable us to add subtitles to your videos ?
For some reason the thumbnail made me think he was going to talk about atomic ammunition, and I think that would be hilarious in war thunder. Instead of spawning in a nuke, you get a tank with a nuclear round. It does remove the possibility of shooting down the aircraft, but I’m mostly saying this because I think it’s funny, not because it would be a good addition to the game.
Both the American DOD and the Soviet DOD equivalent(do not know the name) had developed projects for nuclear tank ammo.
It wnet nowere, but could be added.
well they could always add the Tigerwolf tank and try and make that design somehow manage to exist while breaking multiple laws of physics

Could you provide the data on the firing test between APHE and solid shot? Firing tests back in the day (and sometimes even now) were often fraught with poor methodology or failure to take into account certain variables, and that's not including the ones that were done to purposefully get a certain end result.
For example, in the age of the ironclad Britain (funnily enough the same country you mention) did firing tastes against iron plate that supposedly showed it was proof against the weapons it was likely to face, with the plate stopping the rounds while staying intact. However, it was found in practice that this did not occur, and so they ran the tests again, but this time accounting for the affect ambient temperature might have on the plate (sailing through the North Sea, for example, which would lower the temperature in the iron and make it more brittle). It was found that while effective at warmer temperatures, when in colder climates the iron plate in question would actually shatter rather than stop the rounds.
This is why it is EXTREMELY important to try and look at multiple firing tests and especially post-battle damage reports rather than relying on just one firing test, as that firing test might be absolutely useless for predicting outcomes in the field.
The wich is just “what” lol sounded so funny for some reason
Tanks Ammunitions is why there is a 4th crewmember called the "Loader".
"generally speaking, you dont want to inhale any kind of heavy metal"
*sad music noises*
Hold up
*Depleted uranium shaped charge?*
People have tried basicallyu every metal available to use as a liner. Even gold an platinum among other heavy metals. The Russian 3BK21B shell uses depleted uranium as a liner, to combat the Abrams and Challenger composite armor
It's less the spelling that destroys the crew, is more the over pressure pops the crew like balloons

The real problem with DU (and tungsten darts, for that matter) is their effect on the environment. Shells laying around tend to leach nastiness into the ground and the local water supply. This can be seen, for example, in Kuwait.

Also, service SABOT rounds (apdsfs-t) rounds are a DU core encased in tungsten, the DU is very heavy but relatively soft where tungsten is extremely hard and has a high melting temp...the tungsten can withstand penetration pressure and temp while the DU acts as the weight forcing it through...some targets with light armor or bad armor such as a T-54/55 don't posses enough armor to even breach the tungsten penetrator...basically a sledgehammer driving a thumbtack...the depleted uranium was not put in a sabot round to make it "nuclear" or "dirty", it was put in there to be a heavy core to act as a driving force for the tungsten penetrator because its one of the heaviest materials known to man.
Tungsten has pretty much the same weight as uranium though.
just here to read the comments of all the highly experienced tankers. Wow so many battle hardened veterans in here with so much expert commentary.

I have never heard a more confused and disbelieving “What?” In my life
@Spookston
Please can you share the British tests on APHE rounds? I have not seen it but I have my doubts whether it is a good source to base on.
Purely theorising these tests were done in the 20s/30s with intention of testing shells in AT use. The cannons used would mean a lot especially their caliber - keep in mind in those years Boys AT Rifle was seen as at adequate AT weapon so there is high chance that the cannons used would be QF 2-Pdr knowing that British had APHE ammo for it.
And as we know APHE gets effective after certain point - shrapnel isn't everything and any significant amount of explosives bigger than few grams in closed enclosure like tank is going to cause serious pressure damage.
>APHE explodes as a cone
Well, the thing is - it explodes. It doesn't need a sphere of shrapnel to take out the whole crew, explosion of 2-3 grenades under an armor is enough to take out if not the whole crew, then most of it.
Oh my god, you killed Ke-Ni! You bastard! lol
Spookston trying to correct a military higher-up 😂
Love you spookston, but I wouldn't really say the military doesn't know what we are talking about. I'm a loader for a m1a2 sep v3. U made some great points but not everyone will know the full potential of our ammunition for obvious reasons. Keep up the good work.
Sadly, by today, there are probably people out of the US military knowing full well of it.. If you know what I mean by this
for some reason I couldnt help but think of the meme with APHECBCHEATAPFSDST throughout this whole video
With the APHE one, is spalling the only factor looked at? Because I’d imagine that the pressure wave of expanding gasses from the explosion would do just as much if not more damage than spalling alone
Love that Aliens FireTeam music
3:13 Oh my god, you killed Ke-Ni!
I have a question that I can't find an answer for: why is spaced armor so effective against heat rounds? To me an RPG cage makes no sense because the copper lining is going super sonic, so why would a foot of air make the difference between penetration and non penetration?
As far as I know, spaced armor isn't effective against modern shaped charges anymore. On the contrary, the air gap helps the lining taking proper shape, thus penetrating more. It was effective because older, primitive HEAT rounds quickly lost stability. Btw cage armor doesn't work as spaced armor, it works by crushing and deforming the charge, preventing proper penetration or preventing detonation alltogether
It's really for one reason, with single stage Shaped Charges, all the penetrative energy is created when the shell explodes. What this means is that the penetration of a HEAT shell is limited to a certain maximum distance/depth when it detonates. Spaced armor forces that round to detonate early, meaning that most of the penetrative effect is lost in the time the penetrator is traveling through the air
Because the Copper becomes a Superplastic, which is still a solid form, below the melting point, and between being diverted and cooled, it's damage is significantly minimalized.
That being said, tandem warheads will defeat this.
Like others said there's probably been improvements in HEAT charges, but the spaced armor used to dissipate the power of the charge as it dispersed with the medium change.
Regarding RPG cages, they work by crushing the outer and inner liner of the nose cone together, shorting the piezoelectric fuse and having a high chance of rendering the warhead inert.
It reduces the force of the round on impact with the spaced armor. While there is room for debate for its effectivenesd any add on armor will still increase survivability.
🅱️ESH
The bodies "liquefying" is due more to the Overpressure than Spalling.
Actually, soft caps don't always help against slopes. Dejmian XYZ has a series of 3 simulations of various types of shell striking the Hetzer's 60@60° superstructure armour, 2 of which are 76mm M1 shells, and the uncapped M79 actually performs better than the M62 which is APBCB-HE, for multiple reasons, but one of them is the cap. The cap prevents the tip of the shell from breaking which allows it to be deflected and not bite into the steel, whereas the uncapped shell has the tip break and go up, but the rest of the shell actually pushes through. At least that's how I interpreted the video. Feel free to check for yourselves. They're very short.
the problem with DU is it "self sharpens" it atomizes and when it burns that can get into your lungs,the "it melts people" is from the middle east where people in a car get shot with a tank theres a guy that said two guys with a hose had to hose out the car
So in other words, DU isn't a radiological weapon, isn't a particularly good incendiary weapon, but it is a fairly dangerous chemical weapon.
Yo Spookston, honest question, you think other M1128 versions will make it into WT?
But was the question of pyroforic effect of DU on ammo and fuel explained? It might not literally explode like APHE but should DU have a higher chance to ammo rack/and fuel fire/detonation compared to tungsten penetrators?
Right on you were pretty much on point with every thing. As a chemist I am often rolling my eyes after hearing about how radioactive DU is. It is radioactive but compared to other radioactive isotopes its pretty far down the list. It is VERY toxic how ever, most of the time you have to worry about heavy metal poisoning not radiation sickness. What really annoys me is when people act as if it can cause a nuclear explosion.
Everyone hears about highly enriched uranium and assumes that most uranium is that
Wait hold up. People though capped shells cause a normalizing effect? Granted the only reason I know it doesn't do that is drachinfel has a video talking about the evolution of ship borne cannon rounds
It is claimed by people decades ago, when they don't know much about the subject and let their imagination runs wild.
Then it was popularized by mass media, ie games.
Now, it is everywhere with so many variations going around. And most of the are wrong, including this vid.
Thanks for 3:14 , I just wanted to do it.
I love how the apfsds example is them shooting into a mini van
Edit: it's a fin stabilized apds
I think I saw this video before. They prefered APFSDS to take out suicide bomber cars, because the round would create shrapnels that killed anyone inside.
Mabye it was also about collateral damage, since HE or HEAT would send lethal fragments flying around.
@@kimjanek646 I dont think you need to worry about which round you're using to prevent collateral damage if you're shooting a van filled with explosives...
