Fired without delay fuse:"The 7.5 cm Gr Patr KwK is a conventional high explosive shell with the standard impact fuse kl.AZ. 23. The fuse has an adjustable delay of 0.2 sec. The shell is used to combat troops in the open or with light cover or in trenches. Larger fragments will penetrate light armoured shields and steel helmets. "Fired with delay:"On level ground at low angles at deflection, ricochets are a certainty. These are suited to combat against moving targets in the open or when hidden in trenches or behind houses. If the deflection is great enough to avoid a ricochet, the shell will have the impact effect of a mine, destroying targets under cover, in shelters and in houses."
