I just watched the documentary series “Age of Tanks” on Netflix. It was interesting to see how different countries use tanks against their own citizens.
The Hungarian uprising of 1956 was initially meant to be dealt with by Soviet Union and Hungarian tanks. However, the Hungarian tank crews refused to act against their own people.
By comparison, the British Army had no such qualms when their tanks were ordered onto the streets of Glasgow to put down a 1919 strike. It was the first time in history tanks were used to suppress a civilian population.
