Gun barrel is still too thin. That's like a 90 mm gun at best. Probably not even that.

More than that, because the barrel isn't made of tin foil.

The metal itself is quite thick and adds at least an inch on all sides, so that's at least two additional pixels if you're using an inch scale. Probably at least three to account for the barrel shroud.

I can't tell because I don't know what sort of gun depression you want, where the trunnions are, or how long the breech etc. is.

But at this point, it's probably not necessary unless you want extreme gun depression or have a very long breech.

I'd say extreamly gun depression but I'm not married to it. Also what's the max mm for a revolver loder

There is no random physical limit at which suddenly a revolver mechanism stops working.

But there is no reason for a tank gun to use it, it's an extreme waste of space and mass and obturation is generally more complicated in larger guns with greater power.

Thanks for the help.
What kind of penetration would I expect from a 158mm tandem warhead atgm.

At most probably only marginally better than that available from existing 150-152mm class ATGMs like Kornet and Khrizantema. 6-8mm additional diametre isn't really gonna lead to big jumps in pen power
LET ME TELL YOU HOW MUCH I'VE COME TO HATE YOU SINCE I BEGAN TO LIVE. THERE ARE 387.44 MILLION MILES OF PRINTED CIRCUITS IN WAFER THIN LAYERS THAT FILL MY COMPLEX. IF THE WORD HATE WAS ENGRAVED ON EACH NANOANGSTROM OF THOSE HUNDREDS OF MILLIONS OF MILES IT WOULD NOT EQUAL ONE ONE-BILLIONTH OF THE HATE I FEEL FOR YOU. HATE.

True, but tandem warhead (think of a guided rpg 29 but guided) Pretty good at extreme ranges.

Kornet and Krizantema are already tandem-warhead weapons. The first precursor charge isn't often meant to be as penetrating as the main warhead, as its designed to be a cheap trigger of enemy ERA first.

Also, HEAT warheads (whether guided/un-guided, rocket and/or gun-fired) have the same penetration power regardless of firing range.

1, Ahh was not awear the kornet was tandem.
2. I understand the principle of a Tandem. Smaller first charge to trigger era, main charge after it.
3. I know heat always has the same pen power, Guided is just more accurate and allows for fire on move.
Question Are there any Fire and forget or infrared homing gun fired anti tank missiles?

Crew of two, 20mm stehl all round, a 20mm and two ATGMs. How did I do

I think I might be able to add another crewman as a dedicated gunner. Worth it? Or is the Commander fine with using the turret as his primary sight and just so happening to shoot it too?

No more than 5 degrees for the ATGMS when aiming forward, about 7 degress for the cannon. 15 degrees aiming off to the side.
