Question to the community regarding the sportsmanship and z-fire

[Imp]

The problem really with Z fire is its to good due to the eye of God nature of the game. Units instantly know where Z fire is needed.
Dont take as gospel but I am pretty sure it was common practice for the Germans to carry extra rounds for the MG42 specifically because of its ammo.
Messing with ammo is subjective & if being realistic MGs were Germanys main source of suppresion late war. People would moan if German arty came with the handful of shells they had availabe to fire each day
