Default YT channel with penetration simulations

I came across this very interesting channel which contains several different penetration tests videos:

https://www.youtube.com/channel/UC7r...X2ADwlg/videos

Here are some of the most interesting in regards to the game.

HE hitting light tank armor: https://www.youtube.com/watch?v=PIKsGsdoF-Q

120mm Pz. 531 @ 2km vs upper hull of M1 Abrams:

100mm APHE vs 25mm@ 75 deg.

https://www.youtube.com/watch?v=fih1e1nAiYE

same round vs 20mm @ 81 deg.

105mm APFSDS vs T72B composite armor

same round vs Chieftain turret:

and more.

New video, overpressure simulation, 125mm vs. Leopard 1 early model:

https://www.youtube.com/watch?v=OTmgooJ8mjE

kinda shows the true danger of HE, armor is rarely penetrated, but the crewman that is near the blast is almost certainly a goner.

(I wonder if there is any way of accurately modelling that in the game).

Maybe ( maybe.....) there might be a way to add in a check for crew damage from an HE hit. The bigger the warhead and HEK the higher chance of a * crew casualty damage result but that is Andy's territory but even with SPWW2 if you hit a PzIII with a 152mm HE shell direct fired from a SU-152 that can't be good for anyone near the point of impact in that PzIII

This was done back in April 2021, and is a good example of why sticking to "generic armor thickness" is best:

==================================

RIBBED ARMOUR vs APFSDS & APDS (YOUTUBE URL)

Investigation into the effectiveness of ribbed armour against APFSDS & APDS projectiles. This armour was famously used on Swedish tanks when APDS was the most common kinetic round, as is quite effective against it. The model first matches the experimental set up of a Swedish live fire trial [1], followed by a similar set-up against more modern APFSDS, where the plate has been made thicker and is placed at a steeper angle to stand a better chance against the APFSDS

There is a reason it is no longer used...

https://fromtheswedisharchives.wordp...strv-103-1971/

===========================================

Basically, if you try for a super accurate armor penetration simulation for your game, you end up having to do so many "edge cases" and hacks/workarounds that your "hit/kill" code becomes a convoluted spaghetti mess.

This video is a nice example of an "edge case" -- you'd have a rule that goes: "Strv 103 has +1D bonus to defending against APDS, but no bonus against APFSDS."

Looks like you would need a special oil-filter cap hit rule as well...

Also, the 4 production test plates varied - 61, 65, 67 and 70mm. So you will need a rule for determining each individual tank's armour suite since it is rather variable. The opposite of most wargamers who insist that armour for tank X on facing so and so is always precisely 127.567 mm because some book says so.

Myself, I found the early WRG 1/300 tabletop rules worked perfectly well with thier broad-brush classification of armour being from class "F" (thinnest - halftracks and armoured cars) through class "A" which was King tiger (and others) frontal, the tiger 1 was C front and sides.

We will stick to whole centimetres, unlike some who believe it is more accurate/realistic to use individual mm increments. When 2 tanks off the same asseembly line can be a cm of thickness different.

115mm APFSDS vs. Centurion Mk3 turret (a common 60ies scenario):

Hitting the turret only:

https://www.youtube.com/watch?v=Dg6Vv7lR208

Hitting the gun mantlet and then the turret:

https://www.youtube.com/watch?v=2NKzctGLYXA

Interesting how much penetration is reduced with the mantlet hit.
