What is Artillery?The generic term “artillery” is given to mounted, large-caliber weapons, such as cannons or rocket launchers, used in land warfare and manned by a crew.

RocketsHighly mobile, rapid-fire, surface-to-surface, free-flight rocket and guided missile.Complements cannon artillery to attack deep targets and to strike at counter fire, air defense and high payoff targets.

12 Rockets in less than 60 seconds at up to six aim points.2 Missiles in less than 20 seconds at one or two aim points.

Degrees or Mils?“Mil” is short for milliradian (one-thousandth of a radian)

A radian is a unit of measure for angles.

Mils are more accurate than degrees

In a complete circle, 360°, there are 2 radians (6.283 radians).

1000 milliradians = one radian

There are 6283 milliradians in a circle.

We’ve made things “simpler” by standardizing 6400 mils in a circle.

Page 10: SDZ Construction: Field Artillery (Indirect Fire) Inter-service Resident Range Safety Course (Intermediate)

August 2003

Standard Conversion Formula:

1 degree = 17.777… mils

To convert degrees to mils:Multiply degrees times 17.7845° x 17.78 = 800.1 or 800 mils

To convert mils to degrees:Divide mils by 17.783200 ÷ 17.78 = 179.9 or 180°

Constructing an Indirect-FireField Artillery SDZ

Construct the SDZ for the 155mm Howitzer, PROJ, HE, M107, FUZE, PD, M557.

Dimensions of the SDZ for this weapon system are given in DA-PAM 385-63, Chapter 11, Table 11-1, and Figure 11-1.

Minimum Range + 5550m

Compute Mid-RangeTo determine mid-range, add together the maximum range and the minimum range and divide the total by 2:

Maximum Range 6750m

12,300 ÷ 2 =

12,300m

Mid-Range = 6150m
