I am new to combat mission, but would like to know if constant machine gun fire at a tank will have any effect on its progress. An old fallschirmjager told me that if they had no AT weapons they used to fire MG's at allied armour in italy and the sound inside the tank would be so intense there was no way the tank crew could continue the attack. They had to withdraw becuase of the sheer noise that the machine gun bullets made when hitting the tank constantly.
