Watercolor and pastel on white paper of two six-ton Renault FT-17 tanks (also called "light tanks") climbing a hill. The Renault FT-17 is a two-man tank with the driver seated in front and the gunner standing behind him in the turret. The turret is fully rotating and is mounted with a machine gun. The tank's motor compartment is in back. The tank has two tracked drive wheels which allow it to maneuver over rough terrain and a rear tail to help maintain balance when crossing trenches. The Renault is a French tank and is generally considered to be the world's first modern tank.
