先简短的附上的改动说明：
1、考虑到95式重型可能确实无法胜任4级重坦的位置，95式重型降级成3级HT,91式重型降级为2级HT.
2、Iwakuro再次分家，分出一辆放到4级HT的位置，炮可以根据需要给门合适的。似乎除了这样几乎没有坦克可以完美的放在4级HT了。
3、89式Chi-Ro的线路放到原97式Te-Ke的位置，这样中坦线真的就变成一条名车线了，而且这条线的升级顺序简直就是二战日军坦克的发展史。
4、STA-2放到8级MT的位置，STA-1取代STT成为9级MT，10级还是STB-1不变

之前给明斯克航天局的几个邮箱里分别塞了些双SPG线和双TD线版本的日系坦克树。后来就有工作人员发了合作推荐信给我，在我得到SerB的邮箱地址后我又给SerB发了日系坦克树之前最新的0.9.3版 之前版本的科技树在这个帖子里 http://tieba.baidu.com/p/2323116051
并随图附上了几辆有待商榷的坦克介绍，这些介绍大多是以前看见过就复制下来的英文和俄文资料。
下面发的先是第一部分，是我第一次给SerB发邮件时里的一些内容

然后我又用渣英语说明了下Chi-Ru
Information about Chi-Ru, I found the source of Russian，Detailed reference source。But I'm not sure there is no translation errors, especially on the part of the 130mm gun
有关Chi-Ru的信息我发现与俄文，有详细的引用参考来源，但我不知道有没有翻译错误，特别是关于130mm主炮的部分。
随后复制的是以前俄文的Chi-Ru研发背景，俄文的研发背景这个吧里我之前发过，加上发俄文老是会被度娘吞贴，就不再重复发了
随后是8级以上坦克的顶级主炮，

第一部分内容基本就这些，其实没什么重要的
接下来发第二部分，SerB给我的回信内容
顺便在这里插播一下我以前看到的SerB说过有关Chi-Ru的话
that SerB mentioned in an interview last year is the Chi-Ru. The proposed weight of 48 tons, the thick armor, the large guns, and the proposed suspension all point to something of a scale unprecedented for Japanese tanks.
SerB在去年一次采访中提到Chi-Ru时说这个计划建议是48吨的重量，有较厚的装甲，大口径的炮，和一种对所有日本坦克来说完全不同的悬挂。

第二部分，SerB给我回信了
为了大家看着方便，贴张SerB的图和前几楼的第一部分做个分割线

Greetings!
问候！
Thank you, your variant surely contains some interesting ideas.With your permission, I include our senior historical consultant Petr "Tiger" Bitjukov in this conversation.
谢谢你，你的变种确实包含了一些有趣的想法。如果你允许，我会包括我们的历史高级顾问彼得“老虎”Bitjukov也加入到这次谈话。
I have some questions, primarily about medium and heavy tanks.
我有一些问题，主要是关于中型和重型坦克。

1. Medium tanks:
1.中型坦克：
We have no info about mentioned STA-20 76 and STA-25-90. Do you have some description and graphic materials (photos, schemes etc) about this tank?
我们还没有关于STA-20 76和STA-25 90的具体信息，你有关于这种坦克的一些描述和图形材料吗（照片，计划等）？
Now, we have a weak link between Ch-Ri and STA, so perhaps you can help us to fill it.
现在我们在Chi-Ri和STA-1之间有一个缺失的环节，因此或许你可以帮助我们填写。

2. Heavy tanks:
2.重型坦克
We have similar 1-4 tier tanks in heavy Japanese branch but now we are not sure that Type 95 heavy is strong enough to fight with for example French B2 or British Matilda or American M3Lee properly. Perhaps we can find another candidate? If there was more than one Iwakuro tank (we know only one colonel Iwakuro project) may be we can find more strong vehicle for tier 4. So if you have some materials about Iwakuro project (and other contemporary variants) it would be a great help.
在日系重坦的分支里，我们也有类似的1-4级的坦克，但现在我们不知道95式重型是否强大到足以抗衡例如法国B2英国玛蒂尔达或美国M3Lee。也许我们能找到另一辆候选车？如果在Iwakuro之前有一辆（我们知道有Iwakuro上校的项目），它可能会是4级。我们想找到更强一些的车，所以如果你有一些材料，像Iwakuro（或是同时代的其它变种），那将是一个很大的帮助。

Another question is O-I and post O-I projects. We have mostly only well-known internet reconstruction (but in some weeks we are to close a deal about buying some archives with some schemes included). If you have some materials about Japanese superheavy tanks (O-I and Coastal Defence 140t tanks), it would be a great help, too.
另一个问题是O-I和O-I的后续工程，我们大多仅能根据知名网站里的内容重建这种车辆，（但在这几个星期里我们会达成一项交易，购买一些计划包括一些档案），如果你有一些关于日本超重坦克（O-I和海防140吨坦克）的材料，这也将是一个很大的帮助。

第二部分也不多，但能基本看出SerB对出日系坦克还存在的几个问题
下面第三部分，是我收到SerB来信后做出的回复，
下面开始就是真正的渣英语了，希望SerB和他的翻译还有历史顾问都能看懂

Thank you can appreciate some of my thoughts and give me reply.
The content of these conversations I am willing to share with all people.
Of course, your historical consultant can be added to this dialogue to.
感谢你能欣赏我的一些想法并给我回信，这些谈话的内容我愿意和所有的人分享，当然您的历史顾问也可以加入到这个对话中来。
It should be noted, In fact, I am not skilled in English, Many times I have the aid of Software Translation.
Many of my japanese tanks information is derived from the public network information, Obviously, my understanding is limited.
Although May not find something new to you, I'd be happy to try to answer your question.
需要说明的是，其实我并不能熟练的使用英语，有很多次我都是借助软件翻译，我的日本坦克资料也是来源于公开的网络信息，显然我的了解也是有限的，也许这些不会给你带来新的发现，但我还是乐意尝试回答您的问题。

1. Medium tanks:
Information about STA-20 76 and STA-25 90,I found the Japanese Wikipedia related plan.
Although I am not skilled in Japanese, The posttranslational I know The plan is to start in 1955.
Initial program is to develop a 25 tons 90mm gun STA-25 90.
But after a series of debate, it was suggested that 25 tons is not a suitable weight. Then it was proposed 30 tons 90 mm ??gun STA-30 90.
30 tons of plans to the then Defense Minister and then subsequently reported to be corrected to 32 tons STA-32 90.
These things have happened in 1955.
At the same time, the defense Executive Haikara Osamu by the rise armor useless view. And the emergence of infantry anti-tank weapons. example SS10 Anti-tank missiles.
Haikara Osamu raised 20 tons of 76 mm cannon STA-76 program.
This is the information I have to STA earliest plans. I have not seen these vehicle more detailed information and photos.
I hope the above-mentioned information is useful to you.
1.中型坦克：
关于STA-20 76和STA-25 90，我是在日文维基百科中阅读到相关计划的，我并不能熟练的使用日语，但是我用软件翻译后知道这个计划是起于1955年。最初的方案是制定出一辆25吨90mm炮的STA-25 90.但经过一系列的争论后有研究人员提出25吨并不是一个合适的重量，需要的是30吨方案的STA-30 90,。随后在上报30吨计划给当时的国防部长后又被纠正为32吨的STA-32 90.这些事情都发生在1955年。与此同时身为防卫长官的海原治(Haikara Osamu)深受当时兴起的装甲无用论的观点，和步兵反坦克武器的出现，比如第一代反坦克导弹SS10对坦克的威胁，海原治(Haikara Osamu)提出了20吨76毫米炮的STA-20 76方案。这就是我目前所了解到的STA最早期计划，我也没有见过这些车更详细的资料与照片。希望这些能对你有帮助。

2. Heavy tanks:
Perhaps, You are right. Type 95 heavy can't fight with for example French B2 or British Matilda or American M3Lee.
If there is no suitable tanks in 4 tier,I think the Iwakuro can be split into three tanks into 4-6 tier.
example 6 tier is a Iwakuro-150, 5 tier is a Iwakuro-105, Iwakuro vehicle for tier 4 ,Can give a suitable gun, such as Type 99 75mm Mountain Gun.
Do not know it really feasible to.
2. 重型坦克
也许正如您说的那样，95式重型可能确实无法和法国B2,英国Matilda和美国M3Lee抗衡，如果没有合适坦克填补4级空缺的情况下，我觉得可以把iwakuro拆分成3个级别的车，例如在6级的是iwakuro-150,5级是iwakuro-105,然后4级的iwakuro可以根据需要给一门合适的炮，比如99式75mm山炮。不知道这是否可行。

2. A weak link between Ch-Ri and STA, I think we can use STA-2 to fill it.
I know that STA-2 armored than 61 thick, STA-1 is 7-roadwheel, STA-2 is 6-roadwheel,STA-2 just reduced body length And Enhance the steering ability,So STA-2 Armor is reliable.
STA-3 (completed in January 1960) and STA-4 (completed in November 1959),The two tanks Reduces armor and weight limit, Their design is more close to the type 61.
So STA-2 is a unique vehicle. I think the STA-2 on the 8 tier, will be a good choice. What do you think ?
2. Chi-Ri和STA-1之间的空缺，我觉得可以用STA-2填补，我知道STA-2的装甲要比61式厚，STA-2比STA-1仅仅是少一对负重轮并减少了车身长度，为的是履带转向性有所改善，STA-2的防护性是可以信赖的。直到59年和60年的第二次试制样车的STA-3和STA-4是为了降低成本和限制重量减少了装甲防御。STA-3和STA-4更接近61式，所以STA-2是一辆独特的车，如果8级的MT由STA-2担任，我觉得会是一个不错的方法，你赞同这个观点吗？

3. Coastal Defense 140t, I don't know much about it information, Network some fragmentary information mentioned.
I heard that this vehicle had a plan to install the Navy Type 3 155mm L/60 main gun
There are over plans to install a The Army manufactured by Type 3 203 mm L/35.The prototype of this gun is Navy warships Japanese cruiser Mogami 203mm L/50.
If the "Coastal Defense 140t A" multi-turret on 9 tier,(Type 96 150mm Cannon)
"Coastal Defense 140t B" single turret on 10 tier,(Type 3 155mm L/60)
"Coastal Defense 140t B (203)" single turret on 10 tier TD,(Type 3 203mm L/35)
Such an approach, do you think is reasonable ? What do you suggest?
3. 海防的140吨坦克我了解不多，尽管网络上有些零碎的资料被提到。听说这车还有过安装海军三式155毫米L/60的主炮，还有过安装陆军制造的三式203毫米L/35，这门203舰炮的原型是海军制造的日本重巡洋舰最上级203毫米L/50。如果把多炮塔的海防140吨和96式150毫米重加农放到9级，海防140吨的单炮塔安装海军三式155毫米L/60放在10级。另外海防140吨和陆军三式203毫米L35做10级的TD，这样的做法，您觉得是否合理？
