>>63883774>various types of slat and spaced armor grating works if done rightspaced armor did work, but only against 14.5mm rounds and not against shaped charges
but schurzen was a specially designed, factory-installed, modification and not a field mod
>It's more about the army wanting things to be uniform overall.after experimenting with sandbags, concrete, spiked armor, and mesh armor they found that none of them protected against shaped charges except in very unlikely scenarios or against the much earlier, almost totally replaced, panzerfaust 30
the reason they banned it, at least on an official level, was because sandbagging a sherman could add about 5 tons to its weight, which would result in more losses to mechanical breakdown than would be saved by deflecting any potential shot
the only makeshift armor that was known to actually work was literally welding the front armor of a sherman on to another sherman
which was intended to stop 75mm rounds and not shaped charges
