What's in a Name, Tank

WWI (1914 - 1918) military war machines were called tanks, because they were originally disguised to resemble water tanks. Tanks with cannons were called male tanks and tanks with machine guns were called female tanks.

'Little Willie' was developed in 1915 by British scientists and inventors, and it was the first World War 1 tank. The British produced over 2,600 tanks during the war, but by the end of the war British Tank Corps had only 8 tanks left.
