The use of armored tanks dates back to the First World War when the British debuted the Mark I, the first tank used in warfare, in France during the Battle of Flers-Courcelette, a battle fought during the Battle of the Somme. These early models were rough and unreliable, with many breaking down or getting stuck. Although only a few vehicles made it through the enemy lines, these imposing tanks had the desired effect, and many soldiers from Nazi Germany either fled in fear or surrendered.

These armored vehicles marked a turning point in battle and these early models paved the way for a new generation of fighting and led other nations to develop their own versions. In the early days, the United States lagged behind other nations in tank design and production, and during the Second World War, they employed the use of light tank series Mark II. The U.S. improved on this early model and introduced the more proficient replacement, the M4 Sherman, a medium tank that was a staple of the Allied Forces and was the most heavily armed tank during the war.

The M4 Sherman was a formidable force on the battlefield. While most of the tanks of that era had smaller main guns ranging from 30mm to 90mm, the M4 was outfitted with a 105mm main gun, a .50 caliber Browning M2 anti-aircraft machine gun, and additional machine guns. However, all of WWII’s tanks would play a pivotal role in deciding the conflict, whether in the fields of Europe or the deserts of North Africa, including the medium tank, the Soviet T-34, which is said to have revolutionized tank design. (These are the 23 countries with the most tanks.)

24/7 Wall St. reviewed a catalog of American tanks from Military Factory to determine World War II’s most armored American tanks. These were ranked based on their main gun and their secondary armaments, and we included supplementary information from the Military Factory regarding the type of tank, year introduced, manufacturer, number of tanks produced, and top speed. We also included some tanks that did not see combat and some prototypes to give the full picture of what U.S. tanks were capable of in the World War II era.

In addition to the main gun, all American tanks were outfitted with a secondary armament of machine guns. Most of these armored vehicles had an American-made Browning machine gun standard — some were Browning M2s and others Browning M1919s, which served in an anti-aircraft, anti-armor, or anti-infantry capacity depending on the caliber. (This is the most powerful U.S. Army vehicle engine.)
