Gunn's Tank


What is Gunn's tank? I don't know much about WWII armor, but it's definitely not a Sherman.

Nevermind, I answered my own question. It's an M3 Lee.

Actually, it is an M-3 Grant- the Lee is the M-3 built to British standard- it had a different turret.
In the beginning, they are working on an M3A3 which is the all cast hull version of the Grant-

I'm afraid you've got it backwards; the grant was the British m-3, the Lee was the American.

Also, the tank they're working on at the start of the film is an M-3A1; the M3A3 had a welded hull.

Might as well throw my two cents in. First, the tank is an M3 medium. Period, no further modifiers. It's neither a Grant nor a Lee, as both of those were British references to the same model. The spotting features of the "M3" are the riveted hull and the high profile (cupola) turret. Later variants used welded hulls after experiences in combat because of spalling, the effect inside a tank of rivets being sheared off and becoming projectiles when the hull is struck by a shell. The presence or absence of rivets was not the determinant of the "Lee" v. "Grant" names (as the original M3s had both names in British service). The riveted tanks hurried to the British were called Lees--but when the British had lower profiled turrets put on the hulls to reduce their silhouettes, they called those "Grants". In general the welded variants became known to the Brits as Lee IIIs, IVs, and Vs. The US Army simply called them M3 mediums. They had no nickname.

As a further note, when the British relief column comes up at the end, the two lead M3 mediums are the cast (rounded) hull M3A1 variants (Lee IIs in British parlance), followed by several M2A4 light tanks, which were used only in training during WWII and pre-dated the more familiar Stuart/Honey M3 and M5 light tanks. Their spotting features are their very low profile (virtually no hull), single turrets and prominent driver's aperture.

As I recall, the M3 was powered by a Wright "Cyclone", 9 cylinder, air cooled engine also used in some WWII airplanes. It must have had cylinder compression reduced so it could use non-aircraft "regular" gasoline, I am not sure about that.

The M3 had a high profile making it an easy target for anti-tank gunners. It was a great tank but vulnerable. The M4 Sherman replaced it keeping the 75 mm gun as the main armament and eliminated the 37mm high velocity anti-armor gun in the turret which lowered the profile.
