Comparing: M3 Stuart vs. M3 Light vs. T-127

Developed in 1938 through 1941 on the basis of the M2. Mass-produced from 1941. More than 13,000 vehicles in various versions were built, from the M3 to the M3A3, all of which were supplied to almost every allied nation under Lend-Lease. The M3 tanks were designated Stuart I by the British, while the M3A1 version received the designation Stuart III. The M3 first saw action in the battle at Sidi Rezegh.

The most famous light tank of World War II, with a total of 13,859 vehicles manufactured from 1941 through September 1943. 1,576 tanks (mostly of the M3A1 version) were supplied to the U.S.S.R. under Lend-Lease, and many more to the British.

Developed together with the T-126 at Factory No. 174 during the summer of 1940. Vehicle development was suspended during the preliminary design phase and then discontinued due to problems with the V-3 diesel engine.
