The Medium Tank M2 was a United States tank that was produced in small numbers at the start of the Second World War by the Rock Island Arsenal.
The medium tank M2 was a larger development of the M2 Light Tank. Many components were common or used a similar design, including the vertical volute spring suspension which would be used in later tanks as well. Twin-wheeled bogies were mounted externally, and rubber-bushed and rubber-shoed track proved durable on roads. The M2 had a high superstructure with a sponson-mounted machine gun in each corner. In addition, two more machine guns were fixed in the glacis plate and fired by the driver. Surmounting the hull was a small revolving turret armed with a 37 mm Gun M3 and a coaxial machine gun. The crew comprised of the tank commander, a driver and four gunners. The vehicle provided internal stowage for 200 rounds of 37 mm ammunition and up to 12,250 rounds of .30-06 cal.
The M2 was already obsolete when it entered service, comparing badly with the latest German tanks. Given this, the tank was essentially a stop gap. Employed for training purposes, it did not see combat.
The main production variant was the M2A1, which featured thicker armour, a more powerful engine and wider tracks than the initial M2 model.
For combat, it was a poor design, with thin armour, inadequate main armament and a high profile. But it was important for providing the foundation for the later M3 Lee and M4 Sherman medium tanks. The next medium tank would have to match the German Panzerkampfwagen IV's short 75mm gun. Since no suitable turret had been designed in the US, the Lee was designed first to mount a 75mm gun in the right sponson, which had been tested on an M2. The Lee's gun was mounted in a conventional turret on a modified M3 to produce the first Sherman eight months after the first Lee.[1]
