M4 Sherman

From Conservapedia

The Sherman Tank was America's most mass produced tank during World War II. It was infeior to the German Tiger and King Tiger in fire power, accuracy, and armor. It was too tall to hide being 3.43 meters tall and most would only turn and flee when a Tiger approached. The tank earned a reputation among German tankers as an easy kill, and was nicknamed "Ronson" after a popular brand of cigarette lighter marketed under the tagline "Lights first time, every time"

But it was mass produced and was highly reliable being able to stand all terrain and weather. For every German Panther Tank produced, 15 Shermans were made and for every German Tiger or King Tiger Tank that was produced, 50 Shermans were made. This is how the Sherman prevailed, winning in sheer numbers, not quality. Most Shermans had a mounted 50 caliber machine gun and a 75 or 76 mm gun. The inability of this gun to threaten German tanks led to several efforts to improve firepower. Most famous of these was the Sherman Firefly, a British variant mounting a much longer and more powerful 17pdr gun. The US refused to fit this gun, as they were planning on upgrading their Shermans with a 90mm gun, but all US Shermans remained fitted with the smaller gun at the war's end. Allied air supremacy during the late war allowed much of the work of knocking out the toughest enemy tanks to be performed from the air instead of in head-to-head tank battles.

The Sherman tank was named for Civil War General William T. Sherman.
