First of all, I've been watching this guy for such a long time now and I know for a fact he tries to make these simulations as accurate as possible, he wouldn't even let himself post a flawed simulation, hell let alone even exaggerate the penetration or weaken the armor. Second, there's nothing wrong with a 20mm going through a Bob Semple. I firmly believe that the Bob Semple isn't a tank, it's just a weird ass looking tractor with some guns attached. The only thing protecting the crew is some simple sheet metal that at best will stop a 50 BMG at most angles. Anything bigger than that will penetrate with ease. And mind you, the explosion of a 18 inch shell from Yamato is enough to turn all the crew inside the tank into minced meat from 10m away, even if the tank itself doesn't get penetrated. (For those of you wanting to prove me wrong and bitch about all your reasons on why the Bob Semple is the best tank in the world, I know this is a joke, and I had nothing better to do than to add some realism to this comment section.)

Expect it doesn't even have that. Its max speed on a flat paven road was 24 km/h and on rough ground would be far lower than that. It needed to stop every time it had to change gears. It's incredibly top heavy and would be liable to topple over rough ground. Also it was armed only when Bren Machines so it might be able to fight infantry who lack anti-armour equipment but nothing else

Never saw such heresy, the Mighty Bob Semple could easily stop a railgun at point blank.

I wonder who really doubted that the 20mm would go right through... Im more interested in a rifle caliber steel core shell vs "Bobby the dozer".

So, what I'm seeing is that the Semple Tank would have been quite effective... as spaced armour for another tank. Just strap a Semple to the Glacis and off you go. If you filled the Semple tanks with grenades you might get some explosive/reactive type effects.

How about you hit the Semple with what it would most likely have faced;- Type 5 75mm of the Japanese medium tanks...? I know the results are a bit bloody obvious, but it'd be funny to see how big a hole it leaves. Out of curiosity, is there some way to include a model for a crewmember to these? Even if it's just represented by a simulated wooden board, we'd at least be able to see the volume and speed of fragments they take to the face.

This is part of why war reenactors need to get a larger budget. Personally, I want to see a squadron of Bob Semples go up against an A7V.

I think there is a spelling error, only an 800mm round from Schwerer Gustav MAYBE would dent the armor of The Bob Semple Tank. Still, BST could engage it from much bigger distance and disable it in a single shot, so not a realistic scenario.

Stalinium AT rounds were the only rounds capable of penetration.

I must confess I didn't expect to see this today. And assuming the effective armour values are correct this doesn't bode well for the notion of a 2cm AT rifle round being unable to penetrate the Bob Semple. Wonder what a Bob Semple would stop? M2 Browning? A .50 cal AT rifle? A Pidgeon?

The armor makes it more deadly with all the additionl shrapnels. You'd better be of without walls and a roof. Just a chair to sit and drive and do whatever this thing does.

You forgot the kiwi filler, earliest composite armor that would make the effective thickness 1000mm xd

I think the issue about the Bob Semple's armor is not just because it has a spacing rather due to it lacking layers. Curious though what the 20mm Anti tank rifle Japan uses would do against Bob samples armor if it was doubled. 1 Angled plate, flat, angled plate. Would it help at all.

It is unfortunate that Bob Semple tank cannot survive a hit from an anti tank rifle. Maybe just few more mm of flat armor would had been the key difference between insufficient and barely adequate protection. To me, the unfortunate thing is that people are eager to either criticize or meme about this tank. However, it was genuinely impressive and technically solid vehicle built under war time shortages and haste. What Bob Semple managed to do is nothing short of extraordinary. Instead, people are criticizing it, preferring to do nothing and hope that some higher power saves them. Or in Bob Semple's situation, people would prefer that he would just sit and do nothing to help the army when Japanese are landing on his nation's shores.

How would this armour do against other anti tank rifles of the era? That would show whether it was simply ineffective against anti tank rifles or if the Japanese rifle was overkill.

While this proves 20mm anti tank rounds can indeed penetrate the might Bob Semple, this would require the shooter to have an opportunity to hit the Semple, which let's be honest, can only happen if the Semple let's the shooter hit it

Impossible...

Can you also handle ammunition? Not long ago, I happened to find out through a magazine that the Russian 9.3x63mm 254grain (16.5g) 7n33AP is known to penetrate armor of 10mm at 200m. However, it is questionable that the subsonic ammunition, 9x39mm 250grain (16.2g), sp6, can penetrate armor at 100m to 8mm. 9x39mm has only 754J (556 ftlbs) of energy at 305 m/s (1000 fps), while 9.3x63mm is 4890J (3606 ftlb) at 770 m/s (2524 fps). The two ammunition has more than twice the speed of each other and more than six times the kinetic energy difference, but they have almost the same penetration capability. I don't quite understand this. If you don't mind, could you review this as well?

i wonder how it would be different if the layers are on reverse, if the speed reduction will make the projectile deflect on the angled surface?

Blasphemy! We all know that the Semple will ricochet a direct hit from a Howitzer, let alone a mere AT rifle. On a serious note, the Bob Semple is one of the most misunderstood vehicles of all time.
