Second, don't think that it doesn't matter to increase weight and volume. The reason why modern tanks keep such a volume all the time is because the defensive efficiency of tanks of this size is the optimal solution. The so-called defense efficiency is the comprehensive data of armored hard defense, armored shape, bullet rate and repair rate. Expanding the volume and reducing the speed means that it is easier to be hit and more difficult to repair. Tanks are haggling over the weight, even if your organization can bear it, the ground can't support it. If you use a double-barrel gun, the huge turret mechanism will take up a lot of load values, which will seriously weaken your armor thickness of the same volume level. On the contrary, the defense rate will drop sharply, and engineers with twisted brains will do this.
Third, the modern air force's killing tanks are like things taken out of the bag. The upper limit of the tank's defense force will bully the infantry's light weapons, but all airborne ag weapons are enough to kill tanks many times, which is the limit of land weapons. The armor thickness of the battleship is more than ten times thicker than the apocalypse, so it will be half when it is anti-ship. Do you know why the apocalypse has always been the representative unit of the Soviet Union? Because Apocalypse, a heavy tank, is a classic representative of the Soviet Union's backward tactical thinking, and because it tasted the sweetness of the decisive battle of tanks in the Battle of Kursk, it recognized the theory of the decisive battle of large ships and giant guns, so various wonderful works were born, such as multi-turret Stalin and double-tube heavy tanks similar to Apocalypse (although Americans have done it, people's idea is that double small guns can quickly shoot armor-piercing bullets, while Russian troops are single-minded and high firepower). In the early days of the Cold War, multi-turret religion and multi-barrel religion dared to think that no matter how many optimized designs you adopted, this kind of chariot could not change the result that armed helicopters destroyed 100 vehicles a day. Now MBT has become a local land weapon, and you can't even see the future. You also regard this delusion that existed in the early Soviet Union as a unique "creative thinking". I don't know how to say hello.
