The tank measured a total of 12ft. 11in. in length, 7ft 3.75in. in width, and had a height of 5ft. 8in. A Lycoming O-435-T six cylinder air-cooled engine creating 162 hp at 2800 rpm, and a maximum torque of 332 ft.lbs powered the vehicle. at 2100 rpm. It was capable of traveling 110 miles on a full tank of gasoline, which was 57 gallons working out to be less than 2 miles per gallon. Because of the poor delivery system and lack of performance by the vehicle, the Ordinance Department became less active in developing the tank any further. However the British stayed interested in the vehicle and 260 tanks were delivered to them. The British advanced the tank with an extruder adapter (squeeze-bore) that reduced the projectile from 37mm to 30mm allowing it to travel at a faster rate of 4000 ft. per second. The British used this tank in the crossing of the Rhine River and each Locust tank was credited with killing over 100 enemy soldiers. .
Developed during the same period of time the M8 Light Armored Car "Greyhound- was introduced. The Army was not too pleased in developing an armored car since there were so many tanks available which were capable of doing a better job. After many attempts and failures because the vehicle was too heavy the U.S. army finally adopted the Ford 6x6, which the design called it, the M8 light armored car. "There were over 8500 M8's built between the years of 1942 and 1943."" 3(www.robertsarmory.com A Traveling World War II History Museum. Copyright: 1995) When designing the M8 the army had three main concerns, the vehicles firepower, mobility, and armor. With that the mobility of the M8 was outstanding with it being able to reach speeds of up to 55mph. Enemy gunners had a hard time with targeting and firing because of its excess speeds. On the other hand the firepower was not as outstanding with a 37mm main gun and two other machine guns. The vehicles weapons worked well against that of the Japanese armor but fell short to other more developed countries.
