Description:
The Type 91 was a Heavy Tank built in 1931 which was the precurser to the Type 95 Ro-Go Heavy Tank in game, and had many features carried over from Japans first tank built in 1927: the Type 87 Chi-I. Similar to the Chi-I, the Type 91 had two 1 man turrets on the front and rear of the tank which housed a 6.5mm machine gun, and a larger 3 man turret between the two armed with a Type 90 57mm main gun, and rear facing 6.5mm machine gun. Though the main guns exact capabilities are unknown, it is likley similar to the one seen on the Chi-Ha. The Type 91 has considerably weaker armor than the Type 95 at only 17mm at its thickest, meaning in game, it would have to rely heavily on its above average crew count for survival.
Surprisingly, despite the Chi-I being classed as a Medium tank, and the Type 91 being classed as a Heavy Tank, the Type 91 is slightly lighter at 18 tons, with a more powerful BMW IV inline 6-Cylinder 224 hp gasoline engine. The Type 91 uses the same parallelogram, or swing arm type suspension system as the Chi-I, with 34 road wheels total.
Why it should be added:
This tank could act as a tech tree version of a Japanese heavy tank at a 1.0 battle rating, and would help add to the already limited amount of options Japan has for heavy tank within its ground forces.
