ZhengZhou Police force around 90s

Around the late 80s and early 90s most of the Chinese police force doesn't equip the Type 85(SVD).  
The only choice for medium range fire are picking the Type56semi（SKS）and mount with optic.

there were still some type74 in service currently
but the flamethrower in the picture is the Type 02(A or C), which a lighter and better variant of Type 74.
the main visual difference is the canister number decreased from 3 (type 74)to 2
 




compare to the old Type74 flamethrower

At the end of January, 2018 and after many false starts, the Russian military formally announced the limited adoption of the AEK-971 and AEK-973 rifles.  These rifles feature an unusual counterbalanced breech mechanism which is intended to improve handling, especially during full auto fire.  While exotic outside of Russia, these counter-balanced rifles are not at all new.  In fact, the 2018 adoption of the AEK-971 represents the first success of a rifle concept that has been around for a some time.

Earliest Origins

Balanced action recoil systems (BARS) work by accelerating a mass in the opposite direction of the bolt carrier.  The countermass is of similar mass to the bolt carrier and synchronized to move in the opposite direction by a rack and pinion.  This cancels out some, but not all of the impulses associated with self-loading actions.  But more on that later.

Long before Soviet small arms engineers began experimenting with BARS, a number of production weapons featured synchronized masses moving in opposite directions.  Generally speaking, any stabilization that these actions provided was an incidental benefit.  Rather, these designs were either attempts to get around patents, or very early developments in the history of autoloading weapons when the design best practices had not been standardized yet.  These designs featured a forward-moving gas trap that, of necessity, needed its motion converted into rearward motion by either a lever or rack and pinion.

The Danish Bang rifle
 
At around the same time, inventors started toying with the idea of using synchronized counter-masses deliberately to cancel out recoil impulses.  The earliest patent for such a design comes from 1908 from obscure firearms designer Ludwig Mertens:


 
More information on these early developments is in this article on the matter by Max Popenker.
 
Soviet designers began investigating the BARS concept in earnest in the early 1970s.  This is worth noting; these early BARS rifles were actually trialed against the AK-74.
 

The AL-7 rifle, a BARS rifle from the early 1970s
 
The Soviet military chose the more mechanically orthodox AK-74 as a stopgap measure in order to get a small-caliber, high-velocity rifle to the front lines as quickly as possible.  Of course, the thing about stopgap weapons is that they always end up hanging around longer than intended, and forty four years later Russian troops are still equipped with the AK-74.

A small number of submachine gun prototypes with a BARS-like system were trialed, but not mass-produced.  The gas operated action of a rifle can be balanced with a fairly small synchronizer rack and pinion, but the blowback action of a submachine gun requires a fairly large and massive synchronizer gear or lever.  This is because in a gas operated rifle a second gas piston can be attached to the countermass, thereby unloading the synchronizer gear.

There are three BARS designs of note from Russia:

AK-107/AK-108
 


The AK-107 and AK-108 are BARS rifles in 5.45x39mm and 5.56x45mm respectively.  These rifles are products of the Kalashnikov design bureau and Izmash factory, now Kalashnikov Concern.  Internally they are very similar to an AK, only with the countermass and synchronizer unit situated above the bolt carrier group.

This is configuration is almost identical to the AL-7 design of the early 1970s.  Like the more conventional AK-100 series, the AK-107/AK-108 were offered for export during the late 1990s and early 2000s, but they failed to attract any customers.  The furniture is very similar to the AK-100 series, and indeed the only obvious external difference is the long tube protruding from the gas block and bridging the gap to the front sight.
 
The AK-107 has re-emerged recently as the Saiga 107, a rifle clearly intended for competitive shooting events like 3-gun.
 

 
AEK-971

The rival Kovrov design bureau was only slightly behind the Kalashnikov design bureau in exploring the BARS concept.  Their earliest prototype featuring the system, the SA-006 (also transliterated as CA-006) also dates from the early 1970s.



Chief designer Sergey Koksharov refined this design into the AEK-971.  The chief refinement of his design over the first-generation balanced action prototypes from the early 1970s is that the countermass sits inside the bolt carrier, rather than being stacked on top of it.  This is a more compact installation of the mechanism, but otherwise accomplishes the same thing.


 

Moving parts group of the AEK-971

The early AEK-971 had a triangular metal buttstock and a Kalashnikov-style safety lever on the right side of the rifle.



In this guise the rifle competed unsuccessfully with Nikonov's AN-94 design in the Abakan competition.  Considering that a relative handful of AN-94s were ever produced, this was perhaps not a terrible loss for the Kovrov design bureau.

After the end of the Soviet Union, the AEK-971 design was picked up by the Degtyarev factory, itself a division of the state-owned Rostec.



The Degtyarev factory would unsuccessfully try to make sales of the weapon for the next twenty four years.  In the meantime, they made some small refinements to the rifle.  The Kalashnikov-style safety lever was deleted and replaced with a thumb safety on the left side of the receiver.


 
Later on the Degtyarev factory caught HK fever, and a very HK-esque sliding metal stock was added in addition to a very HK-esque rear sight.  The thumb safety lever was also made ambidextrous.  The handguard was changed a few times.



Still, reception to the rifle was lukewarm.  The 2018 announcement that the rifle would be procured in limited numbers alongside more conventional AK rifles is not exactly a coup.  The numbers bought are likely to be very low.  A 5.56mm AEK-972 and 7.62x39mm AEK-973 also exist.  The newest version of the rifle has been referred to as A-545.

AKB and AKB-1


AKB-1


AKB


AKB, closeup of the receiver

The AKB and AKB-1 are a pair of painfully obscure designs designed by Viktor Kalashnikov, Mikhail Kalashnikov's son.  The later AKB-1 is the more conservative of the two, while the AKB is quite wild.

Both rifles use a more or less conventional AK type bolt carrier, but the AKB uses the barrel as the countermass.  That's right; the entire barrel shoots forward while the bolt carrier moves back!  This unusual arrangement also allowed for an extremely high cyclic rate of fire; 2000RPM.  Later on a burst limiter and rate of fire limiter were added.  The rifle would fire at the full 2000 RPM for two round bursts, but a mere 1000 RPM for full auto.

The AKB-1 was a far more conventional design, but it still had a BARS.  In this design the countermass was nested inside the main bolt carrier, similar to the AEK-971.

Not a great deal of information is available about these rifles, but @Hrachya H wrote an article on them which can be read here.

You are right, the Japanese is really fond of the Horstmann type suspension, Although they did not actually bought one of the foreign tank which use that suspension. To some extent the horizontal coil spring suspension largely used by the Japanese tanks was designed by themselves (Tomio Hara). From Type 94 Tankette (the first Japanese tank applied with that suspension) to the mighty Type 5 medium tank their suspension design are all similar. 
Here is an overall picture of Type 97 medium tank's suspension:

 
This is the initial suspension design (road wheel and spring arrangement) on Experimental Type 97 medium tank No.1. It comes basically straight from the standard Horstmann suspension
 
 
 
Hope these will help  

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.

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.

This so called "rod" (sand rod) is used rod form a cavity in T-64  turret, then aluminum is filled into it.
 But this not a case for T-72, as the sand itself remains as filler.

   Now you can drive it in Arma 3 with fully modeled interior. Knowing that game engine it is better to drive it on the roads only. And don't hit road signs, as this will make this vehicle to achieve some impressive speed while flying across the map and hitting a helicopter, generating some hysterical laughs from whole server. Or those terrible anti-tank pebbles on Altis map. 
 

I made a huge mistake, the mark on object 432 are not support structure at all, it simly just a fill inlet.
I‘ve asked Alexei Klopotov and such 'reinforcement bar' were unheared by him. 
If that marking on the top of the turret is 'filler plugs' , i think it is believable.
well...no actual document or assembly drawings....
maybe we have to call @Andrei_bt to help

And if anyone from SH feels like dying on that sword, well, they will almost certainly have backup.
 

Back when I was posting on the WT forums I had a guy tell me that "not penetrated" actually meant "penetrated" in one of my Russian documents because his East German friend said so.

Well being that both hardcore WT/WoT forum posters and pretty much all of Reddit in general (not just the WT section) have a pretty big reputation of being home to some of the biggest autistic basement dwelling horsefuckers on the English speaking web, I wouldn't worry to much about being attacked here by that demographic. Also thanks for more writings.
 
Funnily enough, it was never really Waffentrager that bothered me though, It was the fact he was too connected to Daigensui/Sumeragi that always raised questions though. (if you need to ask who that is, spare yourself the mental agony of finding out.)

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:

And books I used:





 

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

I have finished my translation and started a new topic, you can see it now:
 

Don't worry, I am currently translating my article from Chinese/Japanese to English. I will start a new topic here when I'm done. It is a little hard for non-Chinese native speakers to understand that by only using the translator. (because it contains slang words)  

Looks like these "charts of CIA origin" are no longer interesting after Sweedish tender information )))
  btw "charts of CIA origin" looks like fake.

I forgot to post out my reference:

and help from Mr.Taki.

This is an article simply to show you guys here how Waffentrager is a faker. The original article  ( https://www.weibo.com/ttarticle/p/show?id=2309404213101531682050) was written in Chinese and Japanese. For better understanding I will translate and edit the article and post it here. 
  And I must tell you why I want to reveal this shit: Long time ago I found many sayings from Waffentrager’s blog which I had never heard of, so I turned to my Japanese friend and IJA tank researcher Mr.Taki and asked him to confirm a few of them. In the end it turned out that none of Waffentrager’s article is true. I once argued with him and he not only failed to give out his reference but also deleted my replies! I’m very angry!
 
  Now let’s get started.
 
  At the very beginning I recommend all of you who opened this post to take a look at Waffentrager’s original article, that will help you understand what I’m debating.
 
  Here is the link to the original article: https://sensha-manual.blogspot.jp/2017/09/the-ho-ri-tank-destroyer.html?m=0  
 
  In China we need to use VPN(aka “ladder-梯子” or “the scientific way of browsing the Internet-科学上网” in Chinese)to open that link above so at first I post out Waffentrager’s original post in the form of screenshots in my article. I’ll skip that here.
 

 
Fig.1: I will skip his original article.
 
  Now, I had raised my first question here: Please take a look at the screenshot:
 

 
Fig.2: My first question
 
  In the original article, Waffentrager insisted that the Type 5 gun tank was built in July, 1944 and fully assembled in August. It was also put into trials at the same time.
 

 
Fig.3: Waffentrager’s original article.
 
  But, is that true? Let’s have a look at the Japanese archive:
 

 
Important Fig.4: Archive code C14011075200, Item 4
 
  Notice the part with the red, this is the research and develop plan for the Japanese Tech Research center in 1943, and had been edited in 1944. ◎砲１００(Gun-100) is the project name for the 105mm gun used by Type 5 gun tank. The column under it says: “Research a tank gun with 105mm caliber and a muzzle velocity of 900m/s”. This means that the gun had just begun to be developed and from the bottom column we can know that it was PLANNED to be finished in 1945-3[完成豫定 means ”plan to be finished” and 昭２０、３ means ”Shouwa 20-3”. Shouwa 20 is 1945 in Japan (you can wiki the way for Japanese to count years I’m not going to explain it here)]
  Next let’s move on to the Type 5 gun tank itself, here is the Japanese archive:
 

 
Important Fig.5: Archive code C14011075200, Item 7
 
  “新砲戦車(甲)ホリ車” is the very very first name of Type 5 gun tank, it should be translated into:”New gun tank(A), Ho-Ri vehicle”. “ホリ” is the secret name of it. Still from the column we can easily know that Ho-Ri was also planned to be finished in 1945-3. But under that column there is another one called:”摘要(Summary or outline)”, in this it says:”砲１００、第一次試作完了昭和１９、８”, In English it is: “Gun-100, First experimental construction(prototype construction) finished in Shouwa 19-8(1944-8)” What does it mean? It means that in 1944-8, Only the 105mm gun used by the Type 5 gun tank was finished! If the Ho-Ri tank itself was finished why it was not in the 摘要 column? So how could an unfinished tank mounted the prototype gun? Waffentrager is talking bullshit.
Also from Mr.Kunimoto’s book, he gave the complete schedule of the 105mm gun, here it is:
 

 
Important Fig.6: Kunimoto’s schedule
 
  “修正機能試験” means ”Mechanical correctional test”, it took place in 1944-8, this matches the original Japanese archive(though this chart was also made from original archives). At that time the gun had just finished, not the tank.
 
  Next is this paragraph from Waffentrager’s article:
 

 
Fig.7: Weighing 35 tons
 
  From the archive above(important Fig.5) we can learn from the second large column”研究要項(Research items)” that Ho-Ri was only PLANNED to be 35 tons, and maximum armour thickness was PLANNED to be 120mm, not was. Waffentrager is lying, he used the PLANNED data as the BUILT data. I will post out the correct data below later to see what Ho-Ri is really like when its design was finished.
 

 
Fig.8: 全備重量-約三五屯(Combat weight-app.35t), 装甲(最厚部)-約一二〇粍(Armour, thickest part-app.120mm)
 
  At this time, some of the people might inquire me that:”Maybe the Type 5 gun tanks were really finished! You just don’t know!” Well, I will use the archives and books to tell these guys that they are totally wrong. None of the Type 5 gun tank was finished.
  Always let’s look at Waffentrager’s article first. He said that a total of 5 Ho-Ri were completed.
 

 
Fig.9: Waffentrager said 5 Ho-Ri were completed.
 
 He also put an original Japanese archive(C13120839500) to “enhance” his “facts”.
 

 
Fig.10: Waffentrager’s archive
 
  Everyone can see the”ホリ車,1-3-1” in the document, and someone might actually believe that 5 Ho-Ri were actually built. But they are wrong! Waffentrager is cheating you with “only a part of the original document”! Here is what the original archive really looks like:
 

 
Important Fig.11: Archive code C13120839500, Item 7
 
  “整備計画” is “Maintenance plan” in English, again it was PLAN! The whole plan was made in 1944-12-26. I don’t actually know how Waffentrager can misunderstand this, maybe he doesn’t even know Japanese or Chinese!
 

 
Important Fig.12: The cover of the same archive, “昭和十九年十二月二十六日” is 1944-12-26” in English.
 
I have other archives to prove that Ho-Ri were not finished as well:
 


 
Important Fig. 13 and 14: Mitsubishi’s tank production chart made by the American survey team after the war ends.
 
  From the chart you can only find out Type 4 and Type 5 medium tanks’ record. There is no existence of Type 5 gun tank Ho-Ri, or the”M-5 Gun Tank” in the chart’s way.
 
  Except for the archives, many books written by Japanese also mentioned that Type 5 gun tank were not finished:
 

 
Fig.15: Kunimoto’s record.
 
  “二〇年五月完成予定の五両の終戦時の工程進捗度は、やっと五〇パーセントであり、完成車両出せずに終戦となった。” In English it’s: “When the war ended, the five Ho-Ri planned to be finished in 1945-5 had finally reached 50% completion. No completed vehicle were made when the war ended.”
 
  Here is another book written by Japanese with the help of former IJA tank designer, Tomio Hara:
 

 
Important Fig.16: Tomio Hara’s book
 
“完成をみるには至らなかった” Again he emphasized that the tank was not finished. Also when Ho-Ri’s design was finished its combat weight was raised to 40 tons, not the planned 35 tons. It was only powered by one “Modified BMW watercooled V12 gasoline engine”, rated 550hp/1500rpm. In Waffentrager’s article he said later a Kawasaki 1100hp engine were installed, but obviously that’s none sense. There was really existed a Kawasaki 1100hp engine but that is the two BMW V12 engine(Same engine on Type 5 gun tank or Type 5 medium tank) combined together for Japanese super-heavy tank O-I use. It will take much more room which Ho-Ri do not have.
 

 
Fig.17: O-I’s engine compartment arrangement. There’s no such room in Ho-Ri for this engine set.
 
  And last here are the other questions I asked
 

 
Fig.18: Other questions I asked
 
  I have already talked about the questions regarding C13120839500 and the engine. As for the gun with 1005m/s muzzle velocity, the Japanese never planned to make the 105mm gun achieve such a high velocity because they don’t have the enough tech back then. Also from the archive C14011075200(important fig.4) the 105mm gun was designed only to reach about 900m/s.
 
  So, after all these, how did Waffentrager replied? I will post out the replies from my E-mail(because he deleted my replies on his blog).
 

 
Fig.19: Waffentrager’s first reply
 
He kept saying that my archive is not the same as his and he is using his own documents. I didn’t believe in these shit and I replied:
 

 
Fig.20: My reply
 
  Last sentence, the Ho-Ri III he was talking about is fake. There are only Ho-Ri I(The one resembles the Ferdinand tank destroyer) and Ho-Ri II(The another one resembles the Jagdtiger tank destroyer). He even photoshoped a picture:
 

 
Fig.21: Waffentrager’s fake Ho-Ri III
 

 
Fig.22: The real Ho-Ri I and the base picture of Waffentrager’s photoshoped Ho-Ri III in Tomio Hara’s book. Many same details can be seen in Waffentrager's fake Ho-Ri III
 
  The 4 variants of up-armoured Type 3 Chi-Nu medium tank is also fake, I will post his original article and the confirmed facts I got from Mr.Taki by E-mail.
 

 
Fig.23: 4 models of up-armoured Chi-Nu by Waffentrager
 

 
Fig.24: Mr.Taki’s reply
 
  Waffentrager used every excuses he could get to refuse giving out the references, and finally he deleted my comments. What an asshole!
 

 
Fig.25: Our last “conversation”
 

 
Fig.26 He deleted my comment.
 
  So, as you can see, Waffentrager is really a dick. He is cheating everybody because he think that we can’t read Japanese. Anyway I still hope he could release his reference and documents to prove me wrong. After all, I’m not here to scold or argue with somebody, but to learn new things. Also if you guys have any questions about WWII(IJA) Japanese tanks, feel free to ask me, I’m happy to help.
