This is a WI tipe of question of hipotetical longterm consequences with two ifs;
the StuG is deweloped into a model with a rotating turret and is more eficient in tank duels (yes i know then it wouldnt be a stug but lets say they keep most of the desing and yust ad the rotating turret and change the name), and is mass produced before 1942
and second a fully funcktional and reliable desing for a assult rifle is finished and mass produced also before the end of 1942, lets say the germans see the shortcomings of highpowered carbines somewhat earlier than they realy did in OTL and put more energy into finishing the sturmgewerh
(i know this all makes little historical sence but hell this is AH after all)
