Yeah even though it is a medium tank,and a Panzer II would be the equivalent the M2A4 seems to be the better tank than a Panzer III as it has a bigger engine, ,is faster and has better armor. The LT vz.38/THN is clearly worse while the BT-7 may better, it is faster and has a better gun but has considerably worse armor so the edge isn't overwhelming if it has one. Considering how many were lost in Russia due to its poor armor and unreliability it may be worse.
