Zero if you want to drop the 100mm gun-launcher and move on to smaller and better things.
Otherwise you're looking at about the same penetration to accommodate the gunner and TC, but if you have an autoloader like Expeditionary Tank's turret you can make the ring smaller.

Don't know if you remember it being posted from a few days ago, but the Armada Compendium on turrets document includes a design for an IFV turret that claims no hull penetration. It featured a 25 or 30mm autocannon I think? Can't remember the manufacturer.

Why would I accommodate a gunner? The entire point of such turrets is that they are remote controlled. The crew is nowhere near the thing.
My entire idea is to take a BMP-3 turret and give it a proper bustle autoloader whilst making it unmanned. Thus my crew is all in the hull away from it and I do NOT have someone sitting around surrounded on all sides by ammo.

Generally they use the space which would be occupied by crewmen for more ammunition for the main gun or a reduced turret ring size, since this is more efficient. The rare IFV with an unmanned turret is generally armed with a automatic cannon in the 20-60mm range, as this is more efficient than giving it a silly 100mm potato gun.

The 100mm is important because it can launch ATGM's and deliver proper HE. In fact I am contemplating just a 10cm + MG setup with no autocanon on the side.

Volume of fire is more important than "proper HE" for that matter, especially when an IFV is involved. The amount of stowed kills between an M2 Bradley and a BMP-3 is rather significant. Rarely will an IFV need to use a large bore HE round, and rarely will any target which requires that be particularly vulnerable to 100mm (tanks, pillboxes) versus 120mm or something from a tank operating alongside the IFV.

It's decent enough if you don't target the thickest armor. Since this is a modern IFV I want to give it a top attack fire and forget missile based on the Spike. The smallest of the Spike family is just 75mm in diameter so I should be able to fit the seeker and stuff in a 10cm package. And 10cm should be quite enough to get through the roof of any tank.Volume of fire is more important than "proper HE" for that matter, especially when an IFV is involved.

Why are you assuming I will always have tanks along side my IFV's? Tanks are expensive and I can't well have thousands of them. Certainly not enough to support infantry all of the time. My mechanized infantry formations will greatly outnumber my tank units. Furthermore, my infantry often have to make amphibious maneuvers which again preclude the use of any non floating vehicles such as tanks. The whole point of this setup is thus to give the average infantry unit something that will make up for when they don't have a tank on speed dial.

Spike wouldn't really work in a gun for rather obvious reasons.
2) Sorry, I assumed your officers and budgetmakers are competent enough to know that infantry need tanks in all situations. The USSR realized this, OMG/Unified Corps weren't just masses of BTRs and BMPs, they traveled as fast as their tank battalions could move and bridges constructed, and this was the reason that amphibious capability has declined significantly in Western armies aside from protection reasons

I actually did contemplate 75mm's. But I figured that I really could not fit a proper ATGM into it.Spike wouldn't really work in a gun for rather obvious reasons.
Why not? I mean obviously the missile it self would be different. But a spike derived seeker and guidance combo should work, just as long as I make sure to build the rest of the missile to spec for something that is launched out of a gun.2) Sorry, I assumed your officers and budgetmakers are competent enough to know that infantry need tanks in all situations.

How many tanks does a modern western army have? And how many infantry units? Show me one army, aside from the Soviets and Chinese that can actually field a tank unit for each infantry unit.

2) Spike's "seeker" requires it to be fired out of a tube, not a closed breech cannon, because the operator needs to control the missile in flight with a fiber optic cable.
More importantly, the missile would be unable to see anything clearly until it has cleared the bore, so it won't be able to hit anything.
There is a reason gun launched missiles use weird guidance methods like RF links or infrared.
This is the same reason why an external or box launcher on the side of the IFV's turret is a superior system to a gun launched missile.
Germany in the 1980s had more tanks than it had IFVs, because it had more tank divisions than mechanized infantry divisions (something like 2:1). The US Army could field about 1:1. That's not important though, tanks are rarely necessary in 1:1 ratios and numbers alone are a useless metric. Instead you have 1:3 ratios or 1:4, depending on the number of subunits and resulting divisibility.

APCs are cheaper. But only if they forgo the weapons and sensors that make tanks and IFVs expensive.
You can give your IFV tank-like capabilities. But then it will have a tank-like price tag.

And that one is going to cost a fortune. So an IFV with lesser sensory and other capabilities but with enough firepower to supplant the need for tanks in situations where you only need that big gun seems like a good idea. Even if this thing costs as much as a modern tank it still comes out as cheaper than the projected future tank my army will get.

Not even surprised.
