?Fully upgraded, the Mighty Bentobox is a very strong tank. 300 alpha is unheard of for tier 5 heavies since the removal of 107mm on the KV tank way back then, and the only other tank to have 300 alpha at tier 5 is the French S-35CA with the 105mm gun. Coupled with surprisingly good mobility and extremely good gun handling, it is very very good at peek-a-boom and midrange snapshots. Another important feature to be noted is the -10 degrees of gun depression: You can hulldown peek-a-boom very easily and without a giant cupola on the turret, exposure while doing so is minimal. Last but not least, the armor is decent, there is no frontal "weakspot" to speak of, with some angling it will bounce same tier 75mm~76mm rounds with reliability. +Fully upgraded, the O-I Experimental is a very strong tank. 300 alpha is unheard of for tier 5 heavies since the removal of 107mm on the KV tank, and the only other tank to have 300 alpha at tier 5 is the French S-35CA with the 105mm gun.

?The two 7.5cm may already be unlocked if you have played the medium line. Otherwise, you have the stock 12cm derp gun to use.

The only drawback of this gun is that the premium AP round does not offer significant penetration advantage over the standard AP, and may run into trouble facing heavily armored tanks in higher tiers, so be sure to read the teamlist for expected enemies at each map location and plan ahead.+The two 7.5cm may already be unlocked if you have played the medium line.

The O-I Experimental is a Japanese tier 5 heavy tank.

Development of this superheavy tank was initiated by Colonel Iwakuro from the Army Ministry of Japan. The project was carried out by the Mitsubishi company, therefore the vehicle became known as the Mi-To. In the army, the tank was designated the O-I. Details of the project are largely unknown.

The O-I Experimental leads to the O-I.

Player Opinion

Pros and Cons

Pros:


  • 300Alpha damage, best in class
  • Good Fire control
  • Good reload time, essentially providing good DPM with minimal exposure
  • Good top speed that is easily reached on flat ground
  • 100 ton tank that can deal serious ramming damage


Cons:


  • Largest tank ever at Tier5, easy to hit
  • Poor Camouflage value
  • Armor isn't great
  • Poor Premium round pen
  • Slow acceleration, although given the weight and size it is still unreasonably good


Performance

Fully upgraded, the O-I Experimental is a very strong tank. 300 alpha is unheard of for tier 5 heavies since the removal of 107mm on the KV tank, and the only other tank to have 300 alpha at tier 5 is the French S-35CA with the 105mm gun. Coupled with surprisingly good mobility and extremely good gun handling, it is very very good at peek-a-boom and midrange snapshots. Another important feature to be noted is the -10 degrees of gun depression: You can hulldown peek-a-boom very easily and without a giant cupola on the turret, exposure while doing so is minimal. Last but not least, the armor is decent, there is no frontal "weakspot" to speak of, with some angling it will bounce same tier 75mm~76mm rounds with reliability.


Early Research

Suspension does not have to be researched to mount other modules; therefore players can straight up research the 10cm first and then do the engine/suspension in the order they please.

The two 7.5cm may already be unlocked if you have played the medium line. Otherwise, you have the stock 12cm derp gun to use. The stock derp gun is similar to the Russian U-11 122mm derp gun in performance, but has noticeably slower shell velocity; therefore players should try to get close to the enemy to have a decent chance of hitting the enemy. The stock 12cm leads to both the 75mm guns and the main feature of this box of a tank: the 10cm. The 10cm cannon is required to unlock the O-I and is well worth the upgrade as it is the only heavy tank that does 300 damage per shot in tier 5, and does it with good precision, fire control, and good reload rate to boot. The only drawback of this gun is that the premium AP round does not offer significant penetration advantage over the standard AP, and may run into trouble facing heavily armored tanks in higher tiers, so be sure to read the teamlist for expected enemies at each map location and plan ahead.

Stock suspension is good enough to handle every module, but upgraded one can make the tank noticeably more nimble.


The upgraded engine is quite expensive in terms of XP, but this engine carries over right up the line of heavy tanks, so it's well worth the investment. The radios also carry over up the line.

Historical Info

After the Battles of Khalkhin Gol with Soviet Union in 1939, Japan tried to improve its tank design using lessons learnt from this battle. Many Japanese tanks such as Type 95 Ha-Go light tank and Type 97 Chi-Ha medium tanks were proven to be insufficient to encounter Soviet armored forces. Larger tank design was urgently needed. A super heavy tank project was proposed along with new medium tank designs.


In 1940, Hideo Iwakuro Colonel from the Army Ministry of Japan (陸軍省 Rikugun-shō) ordered the Army Engineering Division to develop a new super heavy tank. Iwakuro Colonel also indicated that the new tank should be at least two times larger than the current Type 95 Heavy Tank(26 tonnes).

The fifth Army Engineering Division carried out the project secretly and completed a prototype by the end of 1940. The 100 tonne prototype was equipped with a 105mm cannon and could carry over one hundred shells for its main gun. Its secondary armament consisted of a 75 mm cannon and a 7.7 mm machine gun.

The frontal hull of the tank was protected by a 75 mm thick armor and another 75 mm steel plate could be attached to provide additional protection. The side armor of the tank was only 35 mm but it could also attach 35 mm steel plate if needed.

During test trials, engineers realized that it would be highly challenging to deploy this tank. The weight of O-I tank added too much pressure on its suspension system and made it impossible to pass through uneven terrain. The prototype was therefore left in the factory and was scrapped in 1944 and its blueprint was later lost in the war.
