LK I - the Leichter Kampfwagen

The German A7V had obvious flaws when it entered service. It had poor off-road mobility, it required an absurd number of crew, and it was so large that its armor couldn't be properly hardened with the equipment available to Germany. Joseph Vollmer began designing a light tank, called the "light combat car" (Leichter Kampfwagen).

Motorcycles of the Great War

One of the vehicles used heavily in the First World War was the motorcycle, which was a replacement for the horse for scouts and couriers. American soldiers used Indian and Harley-Davidson motorcycles, which produced around 15 horsepower and had 2.5 gallon fuel tanks.

The tank that wasn't - the Saint-Chamond

The Saint-Chamond was France's second vehicle considered to be a tank, though to modern eyes it's closer to a self-propelled gun. With a long 75mm in a fixed-forward mount, it bears even less resemblance to a modern tank than the British rhomboidal tanks.

Hauling freight - the Standard B Liberty Truck

In 1911, an article was published in the Infantry Journal urging the U.S. Army to mechanize and replace horse-drawn wagons with trucks. The Army's response was that they already had 12 trucks, and that was quite enough. Of the twelve, three were at the quartermaster depot in San Francisco, one at Fort Sam Houston (Texas), one at the U.S. Military Academy at West Point, and seven in the Philippines.
