The History Of Tanks

The very first tank was used in World War One, which was at the start of the twentieth century. 

It was a British tank, and it was called the Mark I.

It was a heavy tank, but because it had treads it could go anywhere it wanted to, unlike other vehicles.

Unlike today's tank with their long cannons, the early tanks had guns. 

I did research on YouTube, and this is the video I found.

Boy, that tank is as slow as a slug.  According to the BBC, the Mark I tank could go up to 5.9 kilometers an hour.  Here's some other stuff about the tank.
