Byakuya Ai reacted to Monochromelody in Tank “document” misleading
Some of you may have seen this pic recently on WT forum, in some thread arguing the protection of JGSDF Type 90:
Discussion on WT forum
To be straight, the Chinese annotation in the table said it is just a GUESSING.
This annotation could be totally nonsense but unfortunately a barrier between languages prevent you guys see throught it.
In fact, again, this document itself is about JGSDF Type 10 MBT, not Type 90.
Same trick, different people, huh?
JGSDF specification handbook of Type 10 MBT
page 59, Appendix B, performance (regulations) and data
Let's talk about these regulations and how they were made and encrypted.
You may know that Japanese have Hirakana and Katakana, like Latin have letters and capital letters.
As you can see, some of the most crucial numbers and descriptions are covered by a Hirakana or Katakana or Romaji(Latin letters).
These numbers and descriptions were collected and listed in some append book, called Bessatsu(別冊).
When you look up to the append book, just like viewing the answer sheet of an exam paper. But when numbers and descriptions were censored, you'll never know what it said.
For example, the frontal protection:
“耐弾性 - 正面 - 正面要部は、【あ】に射距離【え】m相当存速において、貫徹されない。”
耐弹性 - 正面 - 正面重要部位可抵御【あ】以相当于射击距离【え】米存速的射击，不会贯穿。
It read like this:
Protection - Frontal - Frontal crucial part should withstand 【あ】 firing at a distance of 【え】meter speed reduce equivalent, and not penetrate.
【あ】stands for certain type of ammunition, probably APFSDS, but don't know whether it is production shot or experimental.
【え】stands for certain firing distance, could be 1000 , 1500 or 2000 (meters), but on such a long distance, shot could be effect by wind and gravity, thus cannot aim on the protection area of target vehicle precisely.
The usual solution is to fire from a much closer range, from 200 to 550 meters, while reducing the propellant charge so that the end speed of AP shot could match the speed drop on certain distance. This is an equivalant method.
Some people argue that Type 90 MBT can withstand AP shot (JM33) firing from another Type 90 MBT, on a distance about 250 meters. The source of this statement came from an unknown video clip, which they have never seen. Firing on closer range is for better aim, and they could have use reduced charge to simulate a much longer range, but we cannot prove.
Byakuya Ai reacted to Molota_477 in Vehicles of the PLA: Now with refreshing new topic title!
Modified MBT-2000（many details very closed to the VT-4 mod.2012,but with 6TD-2 engine） and BK1871（the initial prototype of Type-90 II/MBT-2000）appear in a last year documentary video.【央视纪录片】军工记忆-链接世界 CCTV9
The BK 1871 on the left, note its very sloping UFP , and side by side is the MBT-2000 FP-1, FP means "Formal Prototype", which was designed a new hull nose structure.
More pics about BK1871:
There are also another interesting details of MBT-2000 )
Byakuya Ai reacted to Jagdika in WWII Japanese Tanks in China
All photos were taken by myself in year 2016 during my visit to Beijing. Tanks are from the Military Museum of the Chinese People's Revolution and the Tank Museum(currently closed). Enjoy.
No.1: Type 94 Light armored car (Tankette) in the Tank Museum
This is the early version of the Type 94 Tankette. It was found in a river in 1970s. It is the best preserved Type 94 Tankette in the world.
No.2: Type 97 Medium Tank in the Tank Museum
This is a late version Type 97 medium tank. It carries the old small 57mm gun turret but has the revised engine ventilation port. This tank was donated by the Soviet 7th mechanized division before they withdrew from China in 1955.
No.3: Type 97 Medium Tank Kai in the Military Museum of the Chinese People's Revolution
This Type 97 Medium Tank Kai's combat serial number is 102. It belonged to the former China North-East tank regiment. It took part in the attack of Jinzhou against KMT army on 1948-9-14, and did great contribution for knocking out their bunkers and MG nests by shooting and ramming. Thus after the battle this tank was awarded with an honored name:"The Hero(功臣号)“ About the tank itself, it was assembled by the Chinese army themselves by using destroyed or damaged Chi-Ha parts after the surrender of Japan. This particular tank was built up with a normal Type 97's chassis(57mm gun version) early model, and a Type 97 Kai's Shinhoto(New turret for the 47mm gun). However there are other saying claim that this tank was modified by the Japanese. It was the first tank that roared over the Tiananmen Square during the Founding Ceremony of China on 1949-10-1.
The same tank on 1949-10-1. China's tank army origins from old IJA tanks.
No.4: Type 97 Medium Tank in the Military Museum of the Chinese People's Revolution
Sorry, only one photo was taken. This Type 97 Medium Tank has a chassis from Type 97 Medium Tank Kai and a turret from a normal Type 97 Medium Tank. It was merged together by the Chinese army.
No.5: Type 95 Armored Track(Train track) Vehicle in the Military Museum of the Chinese People's Revolution
Only two samples survived. One is in China here and one is in Kubinka, Russia (Maybe now it is transfered to the Patriot Park? I don't know).
Hope you enjoy the photos I took! No repost to other places without my permission.

In case some of the netizens on WT forum and Reddit doubt my source of reference, I will post them out here.
All the original archives I used are accessible for the public can be found in the Japan National Archive center's website here: https://www.jacar.archives.go.jp/aj/meta/reference
And here is the two archives mentioned by both Waffentrager and me:

Many documents and archives regarding WWII Japanese tanks have already been public viewable, there is always someone don't know.
