    70 years ago, January the 2nd, 1951. To the North of Seoul, in the mountains and hills near Go-yang-tong(高阳洞), British 1RUR dug in and fought against advancing PVA forces. 1RUR got a task force called Cooperforce to support, this is a tank unit from Royal Tank Regiment and Royal Artillery, equipped with Cromwell tanks. When Matthrew Ridgeway assigned the order of withdraw in this afternoon, the US force covering British force's left flank quickly escaped from their sector, leaving the British were completed unawared and uncovered. When the night falls, was cold and dark in the vall

    The Al Khalid derived from Norinco Type 90IIM MBT. It was in the early 90s, when India started to test their Arjun MBT. Pakistanis looked for a MBT design that could be produced by herself. Norinco provided their own Type 90IIM prototype, this is an MBT design which comprised many Western components, such as engine and transmission. There were 4 prototypes for Al-Khalid development, namely P1, P2, P3 and P4. P1 has a Chinese tank diesel engine with ZF LSG3000 transmission. P2 has a British Perkins CV12 Condor diesel engine with French SESM ESM500 transmission. P3 has a

    Disappeared for a long period, Mai_Waffentrager reappeared four months ago. This time, he took out another photoshoped artifact. He claimed that the Japanese prototype 105GSR (105 mm Gun Soft Recoil) used an autoloader similar to Swedish UDES 19 project. Then he showed this pic and said it came from a Japanese patent file. Well, things turn out that it cames from Bofors AG's own patent, with all markings and numbers wiped out. original file→https://patents.google.com/patent/GB1565069A/en?q=top+mounted+gun&assignee=bofors&oq=top+mounted+gun+bofors

    Jagdpanzer 38(t) Hetzer, is a famous late-war Jagdpanzer. On the very early version of Hetzer, it did got a muzzle brake, but such device was removed on later models. After war, Switzerland bought some Hetzer from Czechslovakia, named as G-13. Muzzle brake became standardise on G-13. But, have you ever seen a Hetzer with a muzzle brake like this? (below) Some source like Tanks-Encyclopedia describe this as "early production Hetzer with muzzle brake" but I really can't tell which German KwK or PaK have such British style muzzle brake, like those on Cromwell

    https://tieba.baidu.com/p/2377512442 Do you guys know Sherman M60? It's an Israeli-Chilean upgrade version, equipped with an OTO-IMI 60mm High Velocity Medium Support gun, or HVMS 60. This gun is capable for firing APFSDS and could penetrate 120mm/60° RHA at 2000m. Chilean Army also used these powerful guns to upgrade their M24s and M41s.

    Nicholas Noran a.k.a. "Chieftain" mentioned about this in his program "Chieftain's hatch", but it was a mistake. The ИС-4s use a ЗК-steering mechanism, named after its designer. Г. И. Зайчик(1905-1977) М. К. Кристи(1890-1965) According to the ИС-4 heavy tank operator's manual(Руководство по эксплоатации тяжёлого танка ИС-4), published by Soviet Red Army in 1949, the tank could pivot on one track when in neutral position. Pivot on spot is different from pivot on one track. R=B/2 is pivot on spot, R=B is pivot on one track. Some historical do

    The US CD-850 is another instance for triple differential steering system. On the British Merritt-Brown, when the vehicle goes forward, the sun wheel and ring gear of the planetary always counter rotate. On CD-850, when the vehicle goes forward, the sun wheel and ring gear rotate toward the same direction. The neutral steering of CD-850 is similar to the Merritt-Brown system.

    Another approach to neutral steering is the triple differential steering system. Henry Edward Merritt, an engineer and gearbox designer, is famous for his unique invention, Merritt triple differential transmission. The first British mass production tank with triple differential transmission is the Churchill tank. The Churchill tanks have a Merritt-Brown H4 gearbox, 4 stands for four gears forward, H stands for horizontal, because the two rows of gears in the gearbox are horizontally located. A great advantage of Merritt's design is compactness. The transmission incorpora

    T-14 Armata uses double differential steering systems and is able to neutral steer. Some Russian prototype MBTs can also perform neutral steer, like T-80UM-1 Bars and T-80UM-2 Black Eagle. The first Russian tank with neutral steering is Object 770 experimental heavy tank.

    Yes, Soviet tanks started to have dual-flow transmission after WWII, like Объект 770 heavy tank, Объект 906 amphibious tank and so on. The МТ-ЛБ transmission is similar to АТ-Л artillery tractor's transmission, which is also dual-flow transmission.

    The neutral steer, or pivot steer, means the tank drive one track forward while the other track backward, to perform a turn-on-spot. The very first tank with neutral steer, believe it or not, is the German A7V in WWI. Here is the transmission of A7V. The transmission incorporate two independent gearbox, each connected to a 100-hp engine. The gearbox use clash gears to select speed, and bevel gear to select forward or reverse. It's easy to perform a neutral steer. Those tanks with electric transmission(St.Chamond, Porsche Tiger, etc.) can easily perform

    Sad to find out there is little information about AMX M-4's ZF transmission. ZF's official website mentioned that they converted a Entwicklung-Series tank transmission to meet French 1000-hp AMX M-4 tank design. This ZF-type transmission was widely used among early post war French heavy tank programs.

    From a Japanese magazine PANZER screenshot, it says: This is a Type 61 tank with a sort of ad-hoc spaced armour, using for target practice in exercise. The armour plates surrounding the turret and side skirts make it looks like a WW2 German Panzer IV. The crew tried to pull out a practice round stucking in the side skirt, this round was fired from a recoilless rifle. According to the vegetation of the exercise range, the vehicle was painted in a 4-colour camouflage.

    I've heard that this Type 61 tank with appliqué spaced armour was used for anti-tank rifle grenade firing practice.

    Could you please tell some detail about the development of AMX 10 series AFV? Thank you.
