With the 15cm derp cannon, your play style will have to change radically to make up for the shortcomings of the gun's long aim time and poor accuracy. This means that getting up close and personal in any brawl will allow you to negate your gun's main problems and ensure every shell hits. Having knowledge of what might appear in front of your tank is crucial as well, to make sure the correct shell is loaded. The AP shell in the 15cm gun is better than that in the KV-2, with improved penetration. 121mm may not seem like much, but at tier 6, it is sufficient to go through many tanks frontally. In exchange for the better AP shells, the HE shells do not penetrate as much armour, as compared to the ones on the KV-2. However, thin-skinned targets will be wrecked easily by it. When you are bottom tier, the large caliber HE shell will allow you to do damage in all situations, as long as the shell hits your target. | With the 15cm derp cannon, your play style will have to change radically to make up for the shortcomings of the gun's long aim time and poor accuracy.

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:
- Painless stock grind, the stock gun being similar, if not better, to the T-150's top gun
- The 15 cm howitzer has superior handling and AP/premium penetration compared to the KV-2
- Enormous weight makes it suitable for ramming (or getting rammed, if an opponent is foolish enough)
- Very thick frontal and rear armor with no weakspots
- Good viewrange
Cons:
- One of the largest tanks in the game, can be difficult to maneuver
- Low top speed and poor mobility
- Slow reload and aimtime on both guns (especially the howitzer), poor accuracy
- Thin side armor offers little protection, the sides are very large and penetrating shots there can lead to ammo rack damage
- While thick, the armor is mostly flat; a primary target for artillery and premium rounds
Performance
The O-I takes a major leap forward in terms of armour, doubling the frontal and rear armour thickness, compared to your experimental brother. However for this huge improvement in armour protection, the mobility and agility of the tank is sacrificed, due to the tank getting 50 tons heavier, while retaining the engine from the previous tank. It will feel extremely uncomfortable to play coming straight from the O-I Experimental.
In terms of firepower, the O-I has it in spades. Stock, the tank comes with an excellent 10cm gun capable of going through any tank you might have to face while dealing respectable damage with decent accuracy, but a rather long aim time. There is a second gun for the O-I and it is a 15cm high alpha howitzer, similar to that mounted on the KV-2, with a slightly slower rate of fire, lower accuracy and a horrid aim time. However, this gun can be a lot of fun to play, especially when striking lightly armoured foes which is common at tier 6.
Game play with the 10cm gun allows you to engage targets at a longer range and with a decent rate of fire. It also allows you to play a more supportive role by sniping when you are bottom tier. With this gun, it allows an O-I to laugh at opposing heavy tank's armour, while you effortlessly bounce incoming fire. With the 10cm gun, it also allows you to more reliably handle opposing O-Is.
With the 15cm derp cannon, your play style will have to change radically to make up for the shortcomings of the gun's long aim time and poor accuracy. This means that getting up close and personal in any brawl will allow you to negate your gun's main problems and ensure every shell hits. Having knowledge of what might appear in front of your tank is crucial as well, to make sure the correct shell is loaded. The AP shell in the 15cm gun is better than that in the KV-2, with improved penetration. 121mm may not seem like much, but at tier 6, it is sufficient to go through many tanks frontally. In exchange for the better AP shells, the HE shells do not penetrate as much armour, as compared to the ones on the KV-2. However, thin-skinned targets will be wrecked easily by it. When you are bottom tier, the large caliber HE shell will allow you to do damage in all situations, as long as the shell hits your target.
In conclusion, the O-I is ridiculously powerful for a tier 6 vehicle. It has a flexible choice of guns for different play styles. The O-I has also seen increased use in tier 6 strongholds due to it's armour and derp gun.
Early Research
- Research the Howitzer, its what makes this tank.
- Alternatively, using the 10cm gun on this tank gives it reliable damage and penetration to targets up to tier 8.
- Research the radio(s). Without them, 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.

Historical Accuracy Errata
The 150 ton O-I was never supposed to mount the 10cm gun. It was proposed armament of later modifications of O-I, however.
