M3 Stuart

Although the M3 Stuart was successful in its role of fast infantry support its design did not anticipate the realities of armored warfare and it would be unable to counter opposing armor.  The M24 Chaffee would be a more successful light tank but it wouldn't appear until November, 1944, a mere six months before the war's end in Europe.

Named after the Confederate cavalry general, J. E. B. Stuart, the M3 was well liked by its crews for its speed and dependability.  Nearly 25,000 of the different variations of this tank were produced between early 1941 until the autumn of 1943 when they were officially deemed obsolete.

The narrow hull ruled out a larger turret which meant settling for a 37 mm main gun - ineffective against German armor.  The M3's replacement, the M24, was only three tons heavier but had a tank-killing 75 mm cannon.  The Stuart was often given the role of scout and was successfully used in the Pacific Theater where the Japanese lagged in armor development.

It went where heavier tanks couldn't go.  You're an infantry officer needing to quickly flank an enemy position, this is it.  You want something to suppress machine gun fire, here it is.  You've got dependable infantry support here so long as the other guy doesn't have an anti-tank weapon.  There's the problem.  The M3 armor is flat out thin.

The M3 had a transmission that didn't require shifting and it was modified to use a gyro-stabilizer for more accurate aim while on the move.  Overall it was probably better than other light tanks such as the German PzKw II, or the Soviet T-40 and T-70.  It definitely had greater functionality than the British Bren carrier.  You don't produce 25,000 without having a need to fill.

As an armored fighting vehicle the Stuart won't make anyone's Top Ten list.  It's more likely to be the chosen design for a child's toy tank that fits benignly next to the teddy bear under the Christmas tree.  It's most fearsome characteristic is that pea shooter of a gun that looks like Pinocchio telling another fib.  Whoever thought up this design isn't consumed with visions of vengeance and mass destruction.  Good for him.
