Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The Type 91 Heavy is a Japanese tier 3 heavy tank.

Development of the Type 91, the three-turret 18-ton Japanese tank, started in 1927 and was completed in 1932. The vehicle never entered mass production. Only one prototype was built.

The Type 91 Heavy is the lowest tier Heavy tank in the game and also the earliest heavy tank in Japanese Heavy line. But, Do not let its "Heavy" class trick you; Its "Heavy Armor" is extremely thin (Even some tier 1 tanks had better armor than this tank!), It's also large and slow, Makes it can be very vulnerable from enemy, But, it offers derp gun is powerful enough to one or two shot any tank in the same tier. and the top gun which had monstrous penetration and DPM for its tier.

The Type 91 Heavy leads to the Type 95 Heavy.

Player Opinion

Pros and Cons

Pros:

- Stock gun's HE rounds offers more penetration than AP rounds, yet it deal enough damage to two-shots any tank in the same tier.

- Very powerful top gun combining good damage, penetration and rate of fire

- Fairly small turret with good gun depression

- Tied with British Medium MK.III for second highest HP pools in Tier 3 (280)

- Very fast grinding; It doesn't need new treads to equip heavier equipment, And only had one turret it were used. You can just spamming HE on enemy and can get past this tank in less than 2-3 days without using Free XP.


Cons:

- Despite it was classed as Heavy Tank, Its armor is weaker than some of Tier 1 LT, Even HE rounds from your own stock derp gun will penetrate for full damage.

- Hull surfaces are mostly flat- don't expect to bounce anything.

- Very slow and fairly large size

- Front machine gun turrets limit forward gun depression

- Very weak ammo rack gets exploded often


Performance

The Type 91 should be thought of as a medium tank with a high hitpool, but lower speed. The second gun is very good at taking out same and lower tier targets and in high tiers can be focused on tier 5's.

Historical Info

The Type 91 heavy tank was an experimental multi-turreted tank built in 1931. The tank had three turrets - the primary turret had a short 57mm cannon, while the front and rear turrets were armed with 6.5mm machine guns. The tank had a complicated parallelogram suspension of with two pairs of road wheels per leaf-sprung bogie. There were 17 road wheels per side, giving it a total of 34 road wheels. The Type 91 was considered a failure and cancelled, with development later leading to the Type 95 heavy tank.

Historical Accuracy Errata

The following are consensus errors or inconsistencies which have been identified with the configuration of the vehicle in question and conflict with information available on the public record. The causes for these divergences in the game are normally not disclosed and may be rooted in game balance.

The Type 91 was only ever equipped with the short 57mm cannon, it never had the the 47mm gun (which was developed after the project was cancelled) nor the 70mm cannon.
