Constructing an SDZ for the MK19Construct an SDZ for the MK19 Grenade Launcher firing the M383 HE cartridge.
Map Scale: 1:12,500.
Dimensions of the SDZ for this weapon system are given in DA-PAM 385-63, Chapter 7, Table 7-1.
First, plot the firing point, baseline, target, and gun target line.

Plot the firing point and the baseline.
Plot the target.
Draw the gun target line.
