Foster's, as builders of agricultural machinery, were involved in the production and design of the prototype tanks.

After the First World War, The Royal Commission on Awards to Inventors decided that the principal inventors of the tank were Sir William Tritton, managing director of Fosters, and Major Walter Wilson.

An example of one of the first tanks that were used in the First World War is preserved and on display in the Museum of Lincolnshire Life.
This is a Mark IV.
The tanks were described as "Water carriers for Mesopotamia" during production for security.

The firm used the symbol of the tank after the war on other machinery they built as a trade mark.
