French Light Tank FT-17

This tank first appeared on the battlefield on April 16, 1917. I know this is a World War I vintage tank, but there were still 2,500 in service in the French Army at the outbreak of World War II. As late as 1942, the Vichy French forces deployed FT-17s in North Africa and Syria.
       Obsolete doesn't begin to describe them. The tank has no carriage. Steel plates welded to the track assemblies provides the necessary rigidity. After the fall of France, the Germans scrapped most of them, retaining their turrets for use in the "Atlantic Wall." A few were used as mobile observation posts, some were used for population control and several were fitted with a plow and used to clear Luftwaffe runways.
