The O-I is a Japanese tier 6 heavy tank.
Development of the superheavy tank was started after the Battles of Khalkhyn Gol in 1939. The vehicle was designed as a maneuverable fire unit that was unprecedented in scale—its hull alone weighed 100 tons. Only one prototype was built, without a turret and made of construction steel. Trials were discontinued due to the unreliable engine; at the end of 1944, the prototype was scrapped. The 15 cm howitzer was to be mounted on the tank after its assembly.
The O-I leads to the O-Ni.

Player Opinion
Pros and Cons
Pros:
- Massively powerful 150 MM howitzer; similar to KV-2's 152mm
- Good overall armor, able to bounce shots if properly angled
- Oddly well armored rear, making it usable for reverse side scraping.
- Reasonably agile, considering the size, top speed is achievable.
- Good gun depression, a pattern with lots of Japanese tanks
Cons:
- Huge silhouette, easy to hit, and lots of flat spots on armor plates.
- Slow reload, and horrid accuracy on the Howitzer, but should be expected.
- Radio range is fairly short, with the comparable comparable medium (Chi-To) Having 750M range
- Suffers frequent damage to ammo rack which makes your howitzer gun take over 40 seconds to reload.
- Gold ammo makes your armor worthless.
Early Research
- Research the Howitzer, its what makes this tank.
- Research the radio(s), without it, you can't range in anything over the 300 metre mark. If you went up the Japanese mediums, this should be unlocked.
- Then Tracks, every single degree per second helps.
- Lastly the engine, it doesn't speed it up much, you *may* be able to skip this, but you will most likely want to continue playing this tank, so do so anyway.
