    It depends exactly how and when the HE round explodes.

    If the HE rounds are exploding overhead and throwing shell fragments, the Western paper-tanks should be safe.  In fact, even the aluminum-armored M113 was safe against this sort of threat.  HE round fragments have good initial velocity, but very poor sectional density and aerodynamics, so they are crummy armor penetrators.  The invention of proximity fuses at the end of WWII meant that it got a lot easier to have large-caliber HE shells explode before they hit the ground.  The proximity fuse detected the ground and triggered the shell some distance before it hit the ground.  This meant that the fragments spread from a higher level above the ground and chewed up more area around the shell strike, which is very good for pulverizing infantry.  I'm not sure when the Soviets got proximity fuses, but I doubt they were too far behind the USA.

    If the HE rounds are exploding on contact with the armor of the vehicle, the armor needs to withstand not just the impact of the fragments but also the blast overpressure wave from the explosion.  Here again I would guess that the Western tanks are safe, since 30mm would be considered quite thick for belly armor against mines.  That said, there is a difference in the sort of steel that is ideal for armor against armor-piercing shells and armor that is good for dealing with blast overpressure.  Armor against armor-piercing shells is ideally rather hard but a bit brittle, armor against blast overpressure is ideally tough but a bit soft (toughness and hardness are always a trade-off in steel).

    If the HE round in question is an APHE round that has some degree of structural integrity and is fused to explode a few fractions of a second after hitting something, I think the Leo 1 is screwed.  Regular HE rounds don't really overmatch thin armor well, since overmatch essentially involves the shell bending it's flight trajectory abruptly after hitting something hard.  Regular HE shells have enough of a shell wall to generate fragments, and they're not really well-suited for such extreme maneuvers.  But semi-AP HE projectiles have enough of an armor-piercing body, and usually have delayed-action fuses such that they could probably poke right through.

    So as long as those 76mm guns have APHE, AP or they could pose a threat from the side.  Regular HE, especially with a contact or proximity fuse will probably not work well.  That said, there was also a HEAT round for the 76mm field gun, the UBP-344A.  I haven't been able to find performance, but it could be that those were a threat from the front.

    To be fair, it is one of the most efficient ways to make your pistol more bulky on the market right now.

    Pretty confident this is a 90mm Mk8, not a 95mm gun.

    Though, I found these fresh photos of T-72 Ural scrapped in China. Someone have uploaded them into public networks. (Also,there is someone said that there are still available T-72M and T-72B collected in Plant 617, but have no more photo infos can prove that we have the second T-72. BTW, The T-80U might be located in Beijing Tank museum but do not show to public )

    U-47 found an earlier date, this wasn't covered as heavily, July 1982, also a Romanian based T-72/"Type 64" code name. (Exact day unknown.)

    Isn't the modern mode of civil war one where both sides get propped up by various powers so that nobody gets a decisive upper hand and the host country is comprehensively ruined in ways that neither side could achieve on its own?
     
    If so, isn't one country propping up AND bombing both sides simply the best way to cut out the middleman?

    Do we get to have a description of this thing before we all set out to make a shrine to it? Or do we just grab the image you provided and start printing out pillows?

    What. No. He's the fucking White House press secretary, not Joe from backwoods Georgia. People like him should carefully consider what they're going to say. Not run their mouth like a retard and later apologise.

    According to U-47, June 4th, 1983 from Romania, the tank was put under the codename "Type 64" for security reasons at the time.
