The pinnacle of mobile warfare, the Hatchett 1910 armored car. Two variants of the Hatchett were made, one with duel mounted machine guns, and another with a single 37mm cannon. The Hatchett used a revolutionary 4 cylinder 7.3 liter engine, which reliably produced 100 HP at 1,600 RPM The Machine gun Hatchett could get about 40 MPH on a flat paved road, and 5-15 MPH in off road conditions, while the 37mm Hatchett would get 35 MPH on ideal road condtions, to 5-10 MPH off road. To help with offroad speed, it had rear wheel duelys, and used grousers to increase traction and stop the car from sinking into the ground. The turret could rotate 360 degrees, and its armor was 16mm thick. The entire car weighed 5.5 tons. The 37mm canon could fire at 250 RPM, although sustained fire would often cause the barrel to overheat. The 37mm was also rarer than the machine gun.
