Inter-service Resident Range Safety Course (Intermediate)

The MK19 was deployed in Southwest Asia during Operation Desert Storm and devastated enemy infantry.

August 2003

Constructing an SDZ for the MK19
• Construct 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.

Distance X

• From Table 7-1, find the measurement for Distance X (earth).
• Distance X =

2095m (ˆ2100m)

• Annotate Distance X on the legend.
