  1. Whilst not exactly concerning tanks, do 20mm autocannons need a coax MG in your opinion, a lot of cold war APC/IFV seem not to have one, like the HS.30, Schutzenpanzer 61/73, the US 20mm M113 prototypes and then there are the swedish APC´s.
  2. Didn't T-80UD originally use a diesel, not a turbine?
  3. What allowed the 105mm M68 to be so compact compared to the D-10T? was it primarily in the design of the Concentric recoil system or was the steel used in the M68 stronger to allow it to be lighter, and if the difference was in the steel alloys used what were they, trying to use google to find information on tank gun design and the steels used and trying to find patents of M68 and others seems fruitless.
  4. How stupid is this idea: Replace 12.7mm HMG with 20mm autocannon firing ammunition like the 20mm SHVAK, giving better lethality against infantry with HE and firing Sabot against AFV´s.
  5. Given that today 6.5mm ammo is talked about like its the second coming, why the hell did the japanese switch from a 6.5mm to a 7.7mm round, given that the 6.5 seems perfectly adequate?
  6. How would NERA do against full bore WW2 style AP ammunition?
  7. Well it was only a matter of time before someone made a worse AFV than the Valiant.
  8. Why did china change from 152mm to 155mm artillery, seems strange to me to "abandon" a large amount of stockpiled ammunition. Also why does russian 152mm artillery use cases instead of bagged charges?
  9. Could something like 6.5mm or 6mm Creedmoor be a more sane alternative for a "SCHV" GPMG cartridge like the 6x49 Russian Unified?
  10. This youtube channel has some videos of PLA in combat during a border clash with vietnam: https://www.youtube.com/user/philiplee1027/videos Sorry for the necro, but this seemed the best place to put this.
  11. Some LEO2A6FIN pics: https://imgur.com/a/HT1Fw
  12. Does anyone have a diagram or something on how the 35mm Oerlikon feed system works?
  13. Given that there was talk about chinese welded turrets earlier, wasnt the Type 63 turret also welded?, BTW what reason did the PLA have for moving to 155mm from 152mm?
  14. Also the recoil length of the 105mm is shorter AFAIK, it seems strange that the gun depression was not improved, was it not seen as worth the effort?
  15. Sorry to be just asking questions but does the installation of a 105mm gun increase the gun depression of a Type 59 compared to its 100mm gun variant, i would think that a increase of 1 or 2 degrees could be realistic, but as i have no information on this´i cannot be sure.
  16. Is there any information on when china first got its hands on a T-72?
  17. First post here so don´t know how appropriate my question is, but here we go: Assuming that the 5.45x39 would have a M855A1 style bullet,would its performance be superior to the M855A1 as from what i have read here the 5.45 has some serious advantages in its ballistic properties compared to the 5.56x45.
