lol infantry pack weapon solves all your problems for 2 seconds (not worth the GE!) Mini gun pack

I will say this when Gaijin added the sub tree it was the sadist tree added as others where larger in size when added. Gaijin should have just added the Type 69-IIA and VT-4 (NORINCO) even if people got upset.

Do you know where this value comes from?
To my knowledge, the 15 cm Type 96 shared shells with the 15 cm Type 38 (and 15 cm Type 4) just fixed to different cartridges, which is pretty standard practice for Japanese guns of the same caliber. This should mean they fire the same Type 95 APHE round, just a different velocities.

I’ve seen figures of around 100-125 mm of penetration thrown around for the irl round, but it seems it would suffer a heavy penetration loss from the game’s filler penalty.

There is still the HEAT round with a fair 150 mm of pen, but it’s just not the same as a high pen APHE round. Overall, the gun is an improvement over the KV-2’s, but not to a ridiculous extent.

Compared to the likes of the T30 or other 6.7 heavies, its armor is arguably no more effective, if not worse due to its flatness and relatively thin sides. All the while, it’s still larger and more cumbersome. The secondary 47 mm guns would be great assets, but I can’t quite see them saving this vehicle at 6.7.

I think it would be more comfortable around 6.0 or 6.3 where it’s armor will feel stronger than other heavies.

Let me guess, another 90 USD pack

It was think to be able to use either a 105, or a 155. I think in World of Tank, the 155 is a modifiation.

The penetration I gave is from the 105, the Type 92 canon. It wasn’t largely use, but was highly effective as an artillery. The 15cm gun is the Type-96 howitzer

And as for the pen, I letterally just went to the Enlisted forum.

PS: This link can be very useful, unclassified intelligence on JPN shells with composition and all, how to read shell colors and characters.

(from 6.5 to 405mm)

Edit: I edit a lot, doc is way more complete than I thought.

For the 105mm:

Shell / Projectile Type Approx. projectile weight Explosive / filler Filler amount
Type 91 HE (Long Pointed) High-Explosive ~15.8 kg (35 lb) TNT / picric-type explosive ~1.5–2.0 kg
Standard HE High-Explosive ~15–16 kg TNT / picric explosive ~1.3–1.8 kg
AP Shell Armor-Piercing ~15–16 kg Small HE bursting charge ~0.1–0.3 kg
Chemical Shell Chemical / Gas ~15–16 kg Mustard / choking / tear agents ~2–3 kg chemical fill
Smoke Shell Smoke ~15–16 kg Smoke composition / WP Unknown
Incendiary Shell Incendiary ~15–16 kg Thermite / incendiary mix Unknown
Shrapnel Shell (reported on earlier 105 mm guns, possibly compatible) Shrapnel ~15 kg Black powder bursting charge + balls Small bursting charge
Long-Range HE Shell HE optimized for range ~15.8 kg HE filler Slightly reduced vs standard HE

For the 15cm gun:

Shell / Projectile Type Approx. projectile weight Explosive / filler Approx. filler amount
Type 96 HE High-Explosive ~31–36 kg TNT / picric-type explosive ~5–7 kg
Long-Range HE High-Explosive ~31–33 kg HE filler ~4–6 kg
Incendiary Incendiary ~31–35 kg Thermite/incendiary mix Unknown
Smoke Smoke ~31–35 kg Smoke composition / WP Unknown
Chemical Shell Chemical / Gas ~31–35 kg Mustard / choking agents ~6–8 kg chemical fill
Shrapnel (possible early-war compatibility) Shrapnel ~30–32 kg Black powder + steel balls Small bursting charge
Concrete-Piercing / APHE (reported in some postwar intelligence lists) APHE / bunker-piercing ~35 kg Small HE bursting charge ~0.5–1 kg

PS: We love Japan biologic and chemical war, would perfectly fit in the “wacrime” section of the Japan wikipedia page. Now I want gas shells that have the same effect as the flammetrower. It would be so cool.

Or the opposite as the KV-2 and KV-2 zis-6.
im litteraly having a conversation with myself, I’ll touch grass.

For the 15cm, there is another APHE, just called APHE. It has barrely enough TNT tho… just 5.2 WHOLE KG OF PICRIC ACID. Imagine obliterating an enmy with this. Biggest APHE filler in game. I want it. BAD. (it is around 5.72kg of TNT equivalent)

Yea I agree, theres so much to add to I was disappointed. I have heard about that people were offended though or something like that but I don’t know the whole story for that. But I don’t understand how adding a tank can add controversy. I hope they revisit the idea and add some more Thai vehicles.

Just a small correction Type 59 and of course Type 69 are not based on T-55 but T-54A
Thai Type 69-IIa could also have sideskirts and turret protection as optional since apparently there were some Type 69 observed to have these 2 removed:

Could also save some weight and improve acceleration

When infantry is done cooking I have documents from when chemical weapons where outlawed and decommissioned as everything was documented. Also disposal of Japanese and German after WW2. (hard to find much on Italy though they had some) chemical weapons. The PDFs are on the infantry WIP section. Interestingly the Sherman tank could fire a chemical shell as the shell was compatible with the 75 mm gun. (the shell is basically the smoke shell operationally wise just different fill)

WWII was something in the pacific.
And nowadays we die when the guy next to you farts.
Wasted generation.

If we assume the 150mm frontal armor, with 92mm pen I don’t see it any higher than 5.3. The reload on a 15cm cannon will be very long and the 47s just aren’t doing much at this tier. This thing is also MASSIVE and you won’t even be able to drive it in some parts of the map.

AFAIK the 105mm gun in O-I is just WoT fiction. The 150mm was the only cannon intended for it. Although that 105 has some impressive stats…

The 105 mm Type 92 was considered irl, but would likely only be implemented alongside other overhauls that never came to fruition. Hard to say that it would’ve look like atp. It’s listed here as 100 mm since they usually rounded their 105 mm guns to 10 cm.

That being said, the Type 92 and Type 96 did share a breech, so interchanging the two would actually be pretty easy. But I’d assume the one we’d get in game would match the drawings with the 15 cm Type 96 since that was the plan when the partial prototype was made, and is the most documented variant.


I would be careful using this alone as a source. US documentation of Japanese ammunition in general is routinely incorrect, either due to errors in measuring or recording, or just because they were basing data off limited sample sizes. This particular intelligence report was used as the basis for an incorrect change to the Ho-Ro’s 15 cm ammunition which was only semi-recently fixed. Other subsequent bug reports using this source have been denied since it does conflict with other sources, including other instance of US documentation on Japanese ammunition.

It’s not always wrong, but most numbers you pull from it should at least be cross checked with values from other US reports. Japanese sources are harder to come by sadly, though some exist.


It’s quite possible this round was compatible with the Type 96 howitzer, but I’m not 100% confident of this given the only source of this I’ve seen stating such, and we have no type designation to go off for cross referencing. This is the closest listing I could find elsewhere:

image

Considering the cavity occupies such a huge portion of the shell’s volume, and that the explosives account for at minimum 10% of the round’s mass, it would be classified as SAP and would be hit with a very unfavorable penetration modifier that would drop the penetration to just 55 mm assuming the mass figures are accurate, and that 540 m/s is the correct velocity, however…

I would not expect the velocity to be 540 m/s given its around 9 kg heavier than its usual 36 kg ammunition. They can only increase propellent to such an extent for a lower velocity howitzers without causing excessive barrel wear or risk of damage, I’d expect it be fired with a similar charge to the lighter, common 36 kg rounds, resulting in a sub-540 m/s velocity, likely in the ballpark of 485 m/s.
m₁(v₁)² = m₂(v₂)²
36(540)² = 44.54(v₂)²
v₂ = ~485

Laurelix’s post you linked even lists the unnamed round at just 500 m/s, though for all I know, he just pulled this value from thin air. He’s a rather infamous and an excessively self-confident individual to put it politely. He has presented his calculated ammunition performance as the definitive performance in the past, so take many of his claims with a grain of salt.

For instance, all of the penetration values he listed in the post you linked can be found by just plugging in the masses and velocities he gave into the Gajin DeMarre calculator, adding the filler, and enabling the APCBC modifier regardless of shell type.

If we entertain the 500 m/s figure with the likely SAP modifier, the penetration drops to just 44 mm in-game.
