Yeh im selling this body armour that stops 7.62 rounds… I’ll just casually forget to mention it needs a ceramic backing plate to offer that level protection when selling it to the MOD/British government lmao

Waste of time. He doesn’t want the truth, he wants to be right, no matter what.

I just want gaijin to show me where it says it needs the backing plate to qualify for that protection level

I think you’ll be waiting a while.

I just saw Smin replying soooo

He’s the same guy who makes statements like this and then insults the op for “bad research”


He’s not worth the time

The blocks themselves do have STANAG Level 5 themselves at the specified angle according to the developers. They stop the shell without the need of the back plate:

You literally said the opposite less than an hour ago.

Well apologies, I am relaying answers and information in both directions. I can only pass on what answers I have :)

Either way, the protection does appear to be correct as per the sources.

That is fair, and despite all the stuff surrounding this your work IS appreciated

So the fact that the sources give a very incomplete picture and do not provide realistic data doesn’t matter.

At close to 0 it pens like nothing was there

At 58 it stops on the backplate

And at 64 the block by itself stops it

unlike what STANG 5 says

WIth that it should provide that level of protection from angle 0, and 30 degree to both sides, so 60 degree arc at the front of the block. Not like what we have in game.

Here is a different product showing how stopping thing that fits in STANAG level work

AS it can be seen the bullet does not penetrate the block iself.
Here are tests with Bradley, the IFV ASPRO is advertised on, so it surely should protect from its ammunition.

Plate no pen angle 63

Block stops at 68 degree

You’re misreading the STANAG protection standards. It mentions frontal arc protection, as in a hit directly to the front plate. In order to meet those standards the blocks would need to be able to resist 25mm APDS from 500m at a hit angle of 90 degrees.

Well… is it though?
I certainly think that’s what it means, but then why specify an angle at which it can protect?

so long as it hits the front plate still, so long as it cannot penetrate when fired directly at the flat plate… unless it’s some magical round that defeats sin cos and tan as well as ASPRO HMT it should protect from all angles.

I think the devs are interpreting “Angle: frontal arc to centreline: +/- 30 degrees sides included; elevation 0” as the heading in the protection analysis, which is why Smin’s screenshot shows heading of 30 (and impact of 69 (nice), which I kind of have an issue with as the heading refers to the camera position rather than the impact angle)?

Just a casual shoutout to @Gunjob for being an absolute legend and helping us to get to even this stage after years of being ignored through mountains of bug reports. Some progress is better than none at this stage.

The STANAG standards aren’t about armor plate directly but the general level of protection. So if a vehicle is rated at STANAG 5 it can take a 25mm APDS/APFSDS hit from 500m away from a firing angle of anywhere from 0 to 30 degrees. So, that means if an armor kit is rated or declared as being able to provide STANAG 5 protection it must be able to provide that 0 degree impact protection.

@Smin1080p fixed my post. As you can see, the angle where the blocks by themself stop the round is much bigger than it should be(Ignoring the fact that multiple blocks take part in the proces).

That’s what i thought, the frontal arc to center centre line +/- 30°
