[Client Values; Actual values in

▲

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 O-I is a Japanese tier 6 heavy tank.

この超重戦車オイ (O-I) は、1939年のノモンハン事件の後に開発されました。本車は前例が無いほどの巨大な車体をもった自走式の火砲として設計され、その重量は車体だけでも100 トンに達しました。試作車輌が1輌製造されましたが、この試作車輌は軟鋼製であり、砲塔は未搭載でした。その試験の結果、エンジンの信頼性が十分ではないことが判明し、試験は中止、試作車輌は1944年の終盤に解体となりました。本車は、15cm 榴弾砲を搭載する予定でした。

The O-I leads to the O-Ni.
