The Jeffery Armored Car No.1 was developed by the Thomas B. Jeffery Company in Kenosha, Wisconsin in 1915 with a hull from the Rock Island Arsenal The armored car No.1 was used in General John Pershing’s 1916 Pancho Villa Expedition in Columbus, New Mexico for training.

[1] The Russel company in Canada built a number of armored cars on the four-wheel drive Jeffery chassis.

Forty were added to the "Field Force" that was operating to contain the Mohmand rising of Haji Mullah on the North West Frontier.

Although the four-wheel drive with independent transmission and wide range of gears should have been an advantage, the narrow solid tires negated that and running at more than 12 mph (19 km/h) caused problems with engine bearings.

[2] A different model of armored car basing on the Jeffery Quad chassis was built in Russia by Ukrainian officer Victor Poplavko who was the Odessa city commandant (1917–18), and was known as Jeffery-Poplavko.
