Here is another good one: Abrams upper glacis test.
I wanted to present plans for the future, but I will present plans for the next simulations. I would like to simulate the armor of the Abrams again, as I read somewhere that the thickness of the glacis was increased in later versions, but now I'm not sure. So if anyone has good source it would be helpful. If not, I will do it for 38mm, but with a side angle, so that the total inclination is 83-84 degrees. I would also like to do one simulation at low projectile speed to test the ricochet. One of the slower APFSDS is the OFL-90-F1 (1275m / s).Also it looks like hes looking for info for another Abrams test. AFAIK the upper glacis thickness was never changed from the original 38mm plate.

The barrel tech. A joke. We've had the tech to make these barrels for 30 years.Dang, I was hoping they started making small caliber stellite lined again. Its probably just their CHF barrels with extra thick chrome lining.

Did they seriously take the effort to design the front to make it look like a snake?

All these "assault" belt feds are a bit of a joke. I am glad they're trying, at least.
Im more curious about their barrel tech than the gun itself.
Another interesting note is that there are no operator barrel changes with EVOLYS. They’re so confident in the metallurgy of the barrel that you won’t have to swap barrels during sustained fire. Barrel changes will require tools and about two to three minutes to accomplish.

If they wanted to compete with the Knights LAMG they could have at least introduced a constant recoil system. The side feed only is interesting but it makes the receiver + feed "tray" overly bulky, they must be joking if they're telling people this chunky boy MG can be used like an assault rifle.

2) I believe that the heavy ERA designed specifically to counter KEPs is designed to snap the projectile. Other reactive armors don't necessarily work the same way. I've seen papers on ERA with low-density ceramic and polymer flyer plates, and it apparently works as well as steel on a weight basis. Look up "The Defeat of Shaped Charge Jets by Explosively Driven Ceramic and Glass Plates" by Paul Hazell if you have access to journals and you're curious. That said, there may be some use of heavier materials in reactive armor arrays. @SH_MM is of the opinion that the depleted uranium in the Abrams' armor is incorporated into some sort of NERA, although I personally suspect otherwise.
Im curious if other properties of the material besides just its density and hardness have more of an effect on the flyer plate/projectile interaction. In this guy's models going from HHS to tungsten alloy doesnt seem to have a major difference other than a bit more upward deflection. It seems to hint at things like heat capacity might be at play when resisting the atomizing of the plate and projectile eating up more energy.

The programmatics speak is so bad the presenters have a hard time reading it out loud.

Not much difference than how the fighting in Syria is done, except with less Hell Cannon.

More ballistic data for the data gods. All with a 52k psi max. I wonder if people will be throwing away their 6.5 Grendels for this. Bill Alexander might be sweating right now.
Falls in line with the 18" barrel data from the TAP load.

Yes.
Seems to be a recurring pattern in both the Western and Eastern Block. The IAR is always followed up by a belt-fed to replace or supplement it.

Vladimir Onokoy about it.
Is this the thing they were talking about in July?

Anyone have the skinny on Hornady's 6mm ARC? I like that they're using 6mm VLDs but not a fan of the 6.5G as the base cartridge. Is it reinventing the wheel or is there and actual performance gain.

The new Japanese raifu dubbed the Type 20. Also looks like they adopted the HK striker fired pistol.

CROWS-LP
Dumb people are dumb and where would you store the missiles?
On March 21, Gen. Robert Abrams, commanding general of U.S. Army Forces Command, stated FORSCOM’s position is that the Army should “immediately stop the fielding of CROWS-LP [Common Remote Operating Weapon Station – Low-Profile] systems to Forces Command Armored Brigade Combat Teams (ABVT),” in a memorandum directed at the vice chief of staff for the Army, which was obtained by Task & Purpose.
The memo goes on to say, “The CROWS-LP system does not correct tank commander visual and fire control issues.”
Ten days later, Army Acquisition Command issued a stop-work order to CROWS Low-Profile manufacturer Kongsberg Defence & Aerospace, according to a copy of the order, also obtained by Task & Purpose.
The problem is, nobody from the Army or the Defense Department seems to know the details of the stop-work order or the FORSCOM memo.I guess it never came to pass.

Probably not, having a CROWS-J on an Abrams is also extremely unlikely.
Wasnt there a stop production order on the CROWS-LP a while back? What CROWS are the M1A2C shipping with?
I wouldnt mind the Abrams with a CROWS-J, not because it would be useful, but so that people can stop saying "Abroomz sux cause no gun launched missile"

And people think Im joking when I say the best Cold War battle rifle was the SVD.

I understand the intent, but a lot of me says "Just Issue Tracer".
It's a PKM, they're retard accurate . They can not only count to Potato, they can shoot minute of potato.
So you're saying if I shoot my AK upside down it will be retard accurate?

I don't think it matters. When I design an EPR, I usually try to balance the masses of the two parts at least roughly, but to save time a lot of what I do is iterative based on older works. So some of the relationships are copied over several times from decisions made by me 2-3 years ago.
I heard from a little bird that the mechanism for yaw independent fragmentation has to do with fluid expansion starting in the gap between the penetrator and jacket. Perhaps there is a ideal location to optimize flow into the gap to initial expansion.
