    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.

    Israeli AFVs

    Okay, I got a little request here: 1) @LoooSeR , some of these videos are reposted in Otvaga. I usually post them here first, so they also get reposted here numerous times. 2) @asaf , the THOR system is an old one that was likely only activated because it was nearby. It did not enter service in large numbers, and it's unknown whether it will continue operating for long. 3) Please don't link news articles in Hebrew. Try finding its equivalent in English, but if you don't find one then at least translate it for the others. Since it was already posted, I will do the translation if anyone is interested: Crusher of the Dahieh Saturday eve, July 2014. The ground maneuver phase of Operation Protective Edge commences, and with it one of the most complex battles the Golani had seen in the last 20 years. Notes: Dahieh is a quarter in Beirut, likely mentioned because the new howitzer has sufficient range to hit it from Israeli territory. Golani is a frontline mechanized infantry brigade. After days of warnings, where leaflets written in Arabic were dispersed, radio and TV messages on Palestinian channels, and phone calls to civilians, and smoke shells were fired into village surroundings, began the "softening" phase for the artillery, who fired up to the first line of houses. At its end, Isaac Turgeman, commander of the 36th division gave the green light for the 4 brigades under his command to move deep into Palestinian territory. Golani fighters made their way into the heart of the Shujaiya neighborhood in the Gaza strip to locate attack tunnels that were dug under the cover of Palestinian houses. The tunnel array was defended by the elite Shujaiya battalion of Hamas, which included 860 veteran warriors that prepared for years for an IDF ground maneuver. The "reception", some would call it a well planned ambush, included advanced AT, mortars, snipers, IEDs, and defensive tunnels dug under the houses to help the terrorists fire and vanish under the ground. The night began with the injury of an armor officer, and the friction further increased. A Golani APC was hit and caught fire without being able to extinguish it, and 7 warriors died. Note: It was an M113 APC that wasn't even supposed to be used there. Later it was discovered by the high echelon that Oron Shaul's body was kidnapped using a nearby tunnel. The Shujaiya battalion's fire intensified, and the brown brigade (Golani) paid their price. The then-Golani-commander Rasan Elian was injured and had to evacuate, and later 3 battalion commanders, including one of the recon battalion, were injured and also had to evacuate. The command chain was shaken and disturbed, and the 36th division commander received an ever elongating list of killed and injured men. The ground forces tried to suppress the fire sources and direct aerial firepower, but stumbled upon effective "firewalls" every time they tried to get out of the line of houses to evacuate injured or to move to safer areas. The effort of the Golanis had shown acts of heroism, but was insufficient. It was dawn. The top artillery officer commanded in those frustrating hours on the fire center in the division command center, and received from the Golani support unit commander, info on what's happening on the field and the situation of the enemy. He devised a plan that was not implemented since the 1982 Lebanon war - firing masses of artillery shells on Hamas fighters operating just 100-150 meters from the Golani troops, while heavily risking IDF soldiers as well. The firing plan had to be based on quality and effective intel, and the division intel officer helped create a very clear picture of the enemy location. At 09:00 the artillery officer realized the brigade firing plan had to be converted to divisional firepower - and he relayed to the 3 artillery battalions of the division that they're under his command. In parallel, a building collapses on a Golani force, and the intel officer draws on a digital map the layer of information that is required to hit concentrations of the enemy. He also assembled a rescue plan for the injured. The artillery officer then explains to the division commander why this extraordinary action is required, and stresses "If we don't do this we won't evacuate the injured. There will be none else to help the Golani". Turgeman approves the plan but under one condition: The Golani troops will withdraw to a pre-determined line and enter the Namer APCs, a condition that was based on the assumption that these vehicles will withstand the attack despite the great security risk. After thorough analysis and corrections, the firing plan was approved. Every battalion was asked to prepare 200 artillery shells, and fire them to the pre-determined areas. The fire rate and accuracy were critical. It was clear to everyone that some of the fire would go right above the heads of the soldiers on the ground, and some of it would be fired to just 100-150m from them - far below the pre-set safety bar. In parallel, the artillery officer gave the air force officer an urgent firing procedure that focused on several high rise buildings. The action was set for 10:00, amid heroic efforts by the Golani fighters to evacuate the injured under fire, but not everything went smoothly. An operational dialogue between the battalion commanders to the fire center commander, centered around the plan and focused on the fact that it has crossed the safety lines on which they trained from the very beginning. The fear that the shells - weighing 43kg - would hit the ground troops was very much real. The dialogue was professional and to the point, and ended with the support of all commanders for this plan. "I trust you", he stressed. Later, the artillery officer explained to the cadets of the IDF national security academy, that what gave him the great confidence to pull off this plan was understanding of the artillery profession, understanding the doctrine, his personal acquaintance with the battalion commanders' and understanding their quality, understanding their high level of professionalism, and understanding the tools (howitzers) in the batteries. At 10:10 the command was given, and for 45 minutes 600 shells were rained on the battle zones of the Shujaiya neighborhood. The Golani fighters told "The ground shook like jelly, we've never experienced such thing". Some of the commanders yelled on the comms: "Stop the fire, it's hitting us", and the firing center had to cope with the urgent calls. Aircraft flying over the area provided a live feed of the situation to the computer screens in the Golani brigade command room, headed by Yoeli Or, and in the division fire center headed by the officer. At 11:00 the last howitzer went quiet. The Palestinian territory was silent. Shortly afterwards, an urgent request came from Hamas, through international aid organizations, to declare a humanitarian ceasefire. The Hamas forces did not regain operational capability for the next 24 hours. Golani troops evacuated the injured and prepared anew for an attack. The fire support of the artillerymen lasted throughout the whole 51 days of the operation, and only by the end of it, the scope of the achievement of the artillery and intel in the division was realized: 81 terrorists were killed in the attack, among them more than 10 chief Hamas commanders. The said combat legacy - that underlines the importance of heavy statistical fire, alongside the precise guided rockets and missiles - explains clearly why the security cabinet approved last week the new howitzer for the corp. It is one of the most central projects for the ground arm for the next couple of years, and the delay in its implementation was the result of budgetary difficulties. Some of the cannons that rained fire on Shujaiya were over 40 years - an outdated system with a limited range, whose operation requires a crew of at least 10 men. The new cannon, made by Elbit, will save more than 50% of the manpower as it is semi-automatic, will greatly increase the operational range and rate of fire, and will dramatically improve the accuracy and lethality. Every new cannon will replace an old battery, and will provide the corp with better flexibility for relocation, while its command and control systems will allow connectivity with the other corps. In parallel, the ground arm will finalize by the end of this year a purchase of smart rounds, that will increase the quality of the existing howitzers. Pics from article: The artillery corps is going through, in the last years, more than just a face-lift. He's simply transforming. Aside from the howitzers, the rocket array (MLRS) that includes also a Romach battery that possesses the fire rate and capabilities to work against multiple targets simultaneously, the geolocation array, that said goodbye to the Nurit radar and accepted the Raz radar (Raz - Rav Zroyi - Multi-arm/branch, EL/M-2084). The IDF website also chose to highlight the Kelah David brigade, whose outstanding unit is the Rochev Shamaim, the one that uses small UAVs for the artillery corps. One of the more classified units is Moran, that was established in 1982 and participated since - through using the Spike-NLOS missile - in many operational activities, including precision attacks and hunting rocket launching units. The UAV unit of the ground arm in the artillery corp is a parallel unit to the air force's UAVs, but different in its missions, operational culture, and type of aircraft. Its primary destination is to support the ground maneuvering forces - something the chief of staff Major General Gadi Eizenkot constantly speaks of. These units, and the overall activity of the corp, leads to to one main question: Are the artillery commanders capable of turning it into the ground arm's air force? Unlike in Operation Protective Edge, the next war will require the IDF to maneuver deeper and quicker. The threat on the forces will also be more complex, and will require complex artillery firepower: Warning fire to distance the population, deterring firepower, screening, evacuation, and hitting the centers of gravity of the enemy - command and control centers or concentrations of fighters. Another change on which the corp's revolution is based on is the Hupat Atar system. Uploading the target to a force-wide net allows a wide range of attacking solutions - an especially critical advantage when the enemy against which the IDF deals with, hides most of the time, shows up for short periods of time, and avoids face to face combat, except for unusual raids. Hence, every second in the IDF's reaction time is critical. The massive cuts in the reserve forces and shutting down of units did not go over this corp, and in the frame of re-organization it was decided that whoever stays in the corp will be better trained and better prepared than before. Additionally, the artillery school in Shivta was united with the reserve division - the 252nd division.

    Books About Tanks

    Yeah, he posted a bunch of comments on his book for a 4th time about a month ago, and he seems to have found every obscure semi-history related forum out there to post the same cookie cutter comments. I've been watching Amazon for a used copy, cause there is no way I'm paying full price for a book I know is trash, by a person who seems actually borderline crazy, or at least a huge asshole no one can stand. I'm somewhat surprised he never showed up here in the Sherman thread or this one. P.S. welcome to the forums! You will fit right in!

    His specific argument is that a tank's actual power to weight ratio is not the gross horsepower of the motor divided by the weight of the tank, but rather the sprocket horsepower divided by the weight of the tank. Sprocket horsepower is the gross horsepower of the engine minus losses from the cooling system and the transmission. Since the Merkava mk III is supposed to have a particularly efficient transmission, its actual power to weight ratio isn't as bad as the more simplistic numbers would suggest, and in fact the merk has no worse of a power to weight ratio than tanks that have more powerful engines, but less efficient transmissions. I don't buy it. Here is the full quote from Technology of Tanks concerning the difference between gross horsepower and horsepower available at the sprocket: So the Merkava has a transmission that never dips below 71% (he claims), and it's up against transmissions that are only doing 61% efficiency. That's a 16% improvement in power actually delivered to the sprocket. But so what? A 1500 horsepower engine has 25% more gross horsepower than a 1200 horsepower engine, so a 1500 horsepower engine through a shitty Allison transmission is still going to be putting more ponies into the drive sprocket than a 1200 horsepower engine going through a magical Israeli transmission. The numbers don't add up. It's horseshit. On top of that, in the particular instance of the Abrams vs the Merkava, the Abrams has a higher percentage of gross engine horsepower available as net engine horsepower because turbines are (nearly) self-cooling, and don't loose significant power to radiators or fans.

    Oh.. OH this post! Yes, a common 3 ton engine crane would do. Pallets to take the mill and engine. "Cribbing is always your friend" when dealing with tanks. Also, HUGE wrenches. And you will break them. Harbor Freight, cause Snap-On will tell you to fuck off after the second swap. I have personally experienced this. You do end up making a lot of tooling. You'd best be a semi-competent machinist, cause you will be making tools, and parts, and fixtures, etc... Learn to work on and repair forklifts, because YOU WILL NEED ONE. It will be your most used tool, other than a 12 Oz ball peen, and a 12" crescent wrench. Buy the BIGGEST you can afford. ALL engines can be timed with either a light, or a pointer. If it lights at first crank, who the fuck cares how you timed it?

    Talk about Type90, i got some information from Chinese document which mention about the armor composite used on Type88 which is the prototype for Type90 recently. Not sure the exact truth but i would like to share. “Japanese Type88 tank's turret and hull composite armor were trying to use different ceramic material (Alumina、Silicon oxide or Silicon carbide ceramic cut in rectangle or hexagon),each layer using binder to bonded together. The protection of this armor can reach up equal to 400mm thick of armour steel (BK) and is capable of defeat 120mm high density KE projectile (muzzle velocity>1600m/s) fired from 200meters at 0 degree, and also capable to protect against the 120mm HEAT shell which capable of penetrating 600mm of armor. Besides, there are many of different type of armor plate, the use of ceramic material and it's ability of protection giving the armor research development a new direction” image10 Type88 tank's spaced (composite) armor structure. 陶瓷板=Ceramic plate 毫米=mm Other than this,japan seems are developing some kind of Kevlar composite It says:"Japan is currently develop a Kevlar fiber with Titanium alloy or aluminum structured multi-layer composite armor " Of course those are just for the prototype of type90, but we can try guessing the armor from this source: <<间隔(复合)装甲——现代坦克的主要装甲结构>>(1982) (Composite armor--the main structure of the armor for modern MBT) (1982) <<国外复合装甲中非金属材料的应用和研究概况>>(1983) (Summarize of the use and research of non-metallic material in foreign composite armor)(1983) ft.
