This American Tank Shocked the Russians!

For the first time in the world, tanks were used on September 15, 1916 during the Battle of the Somme, 49 British tanks attacked German positions. Some of the tanks were out of order due to breakdowns, having suffered no combat losses, but a breakthrough in the defense was carried out.
From that day on, the tank became an integral part of the armies of the countries.
The major countries continue the race, introducing new types of tanks with new capabilities.
The armor has undergone radical changes over the years, moving from steel plates to composite materials, made of steel, plastic, ceramics and other classified materials, has many layers both inside the tank and outside. The engines of modern tanks develop over 1000 horsepower.
Tank cannons have become larger and more accurate, they can fire various shells and guided missiles.
Finally, computerized fire control, high-resolution optics, laser guidance devices, hazard warnings make the tank an expensive weapon.
The tanks in our ranking are leaders in their class in categories such as defense, firepower and mobility. Often the presence of at least a few of them on the battlefield can tip the scales in favor of one of the opposing sides.
In our list, besides these three indicators, one more important factor was taken into account - cost. It is sometimes decisive when the question arises of adopting a particular tank into service.
