Grunt Work

During World War I, one of the worst jobs in the French army was that of wirecutter, the scout deputed to cut through the wire entanglements set up by the enemy, often unprotected in exposed positions. To improve his chances, the army introduced this one-man tank. From Popular Science Monthly, May 1917:

The device is made to resemble a cannon which it is hoped will be considered by the enemy to be broken and discarded. It is provided with slits and larger openings through which the scout may see and get air. The wheels, though apparently rusty and old, are smooth-running and noiseless, and the legs of the scout, moving cautiously at the rate of perhaps one-half inch per minute during critical times, resemble the drooping muzzle of the gun — or it is hoped that they will.

“It is also considered among the possibilities that the device will be of service when it is necessary for a bold and death-defying dash to be made through showers of shrapnel into the teeth of the foe. But this is problematical since the device is not made for rapidity of movement.”
