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.

AnnoJ26_Type_89.png

3400

The Type 89 I-Go/Chi-Ro is a Japanese tier 2 medium tank.

Developed in 1929. The first Japanese tank with a diesel engine, which served as the main tank in the early 1930s. By the beginning of World War II, the design of the vehicle was already obsolete; however, it was widely used until the end of the war. Vehicles of this type last saw action in 1944 in the Philippines.

The Type 89 I-Go/Chi-Ro marks the end of its Japanese medium line.

Player Opinion

Pros and Cons

Pros:


  • Rate of Fire, DpM, and Alpha Damage is beyond incredible for a tier II
  • Retains well-known japanese gun depression; does VERY good on hill's
  • Slightly larger HP Pool compared to its peer's
  • HE Shells are about on par with the AP shells in terms of penetration
  • Good trainer for the upcoming Type 91 and 95 heavies as they all play similarly


Cons:


  • Sluggish speed and traverse; Hillclimbing is a slow and tedious nightmare
  • Armor is severely lacking for a medium; wont bounce many shots
  • Penetration is bad, even by tier II standards; almost completely useless in tier III
  • Pretty large for a tier II; will draw fire, even from a distance
  • High priority target due to its large calibre gun and soggy cardboard armor

Historical Info

The Type 89 medium tank I-Go (八九式中戦車　イ号 Hachikyū-shiki chū-sensha I-gō?) was a medium tank used by the Imperial Japanese Army from 1932 to 1942 in combat operations of the Second Sino-Japanese War, at Khalkhin Gol against the Soviet Union, and in the Second World War. The Type 89B model was the world's first mass-produced diesel engine tank. The tank was armed with a short-barrel 57 mm cannon for knocking out pillboxes and masonry fortifications, and proved effective in campaigns in Manchuria and China, as the Chinese National Revolutionary Army had only three tank battalions to oppose them, which consisted primarily of Vickers export models, German Panzer Is, and Italian CV33 tankettes. The Type 89 was a 1920s design medium tank, built to support the infantry, and thus lacked the armor or armament of 1940s generation Allied armor; and was regarded as obsolete by the time of the battles of Khalkhin Gol, against the Soviet Union, in 1939. The code designation "I-Go" comes from the katakana letter [イ] for “first” and the kanji [号] for “number”. The designation is sometimes transliterated “Yi-Go”
