Through the help of the Chino Planes Of Fame Museum, 2nd Armored fields two Stuart tanks, an M5A1 model nicknamed "Iron Maiden," and an M3A3 version. The M5A1 model is the more common variant seen in Europe. It has flat sides where the M3A3 has angular sides. Both are in excellent working condition and feature a propane firing main gun which provides a powerful pop and flame.
The turrets are the same. In fact, the newer M5 took the modified turret of the M3A3, which featured space for a radio set-up in the back of the mount. Both have a coaxial machinegun in the turret as well as a bow machinegun on a ball turret. You can see the cosmetic differences below:

Both tanks are part of the 66th Armor Regiment and crew up to four tankers. Because of its light armament and its speed, these vehicles are best suited for reconnaissance and light infantry support. They are extremely vulnerable to anti-tank weapons and guns, and are thus never far from supporting infantry, such as the 41st Armored Infantry or 82nd Reconnaissance.
