SDZ Construction: TOW Inter-service Resident Range Safety Course (Intermediate)

2
August 2003 TOW missiles engage and destroy enemy armored vehicles, primarily tanks.

3
August 2003 The basic TOW Weapon System was fielded in 1970.

4
August 2003 TOW 2 Missile has extended probe. It was first introduced with ITOW.

5
August 2003 BGM-71A Basic TOW: The original TOW missile had a diameter of 5” and a range of 3000 meters.

6
August 2003 BGM-71C Improved TOW (ITOW): This missile includes an extended probe for greater standoff and penetration.

7
August 2003 BGM-71D TOW 2: The TOW 2 and TOW 2A have an improved propellant in the flight motors, and the guidance links have been hardened.

8
August 2003 BGM-71E TOW 2A: The TOW2A has the capability to defeat reactive armor.

9
August 2003 BGM-71F TOW 2B: The TOW 2B Missile incorporates new fly-over, shoot-down technology.

August 2003 Weapon: Ammo Type: Distance X: Distance D: Area A: Area B: Area H: Area I: Area F PDA/CA1/CA2 Map Scale: Map Sheet: Map Series: Map Edition: Date: Name: Legend for the TOW

11
August 2003 Constructing an SDZ for the TOW Construct an SDZ for the Basic TOW (ground launch) High Explosive warhead. Map scale: 1:50,000 Dimensions of the SDZ for this weapon system are given in DA-PAM 385-63, Chapter 15, Table 15-1, and Figures 15-1 and 15-2.

12
August 2003 Plot the target. Plot the missile target line. Plot the firing point.

13
August 2003 Distance X = Annotate Distance X on the legend. Distance X From Table 15- 1, find Distance X. 5000m

14
August 2003 To locate the downrange limit of the Dispersion Area, at Distance X, draw a line that extends 200m to the left and right of the missile target line. The missile target line now looks like a “T”. Distance X 200m

15
August 2003 47° Measure 47° to the right and left of the missile target line. Draw tic marks as shown. Distance X 200m

16
August 2003 From Table 15- 1, find Distance D (ground). 3800m Distance D = Distance X 200m Distance D From the firing point, draw straight lines the length of Distance D through the tic marks just drawn. 47°

17
August 2003 Distance D Connect the lines at Distance D to the “T” downrange. This completes the Dispersion Area. Dispersion Area Distance X 200m 47°

18
August 2003 Area H Area H the Area to the rear of a weapon system (e.g., TOW missile) which contains warhead particles (collapsed- shape charge and warhead fragments) during an “eject-only firing event.”

19
August 2003 From Table 15- 1, find the radius for Area H (high explosive warhead). 3200m Radius of Area H = Distance X Dispersion Area 3200m

20
August 2003 To the rear of the firing point, scribe an arc with the radius of 3200m from the left to the right limits of the Dispersion Area. Distance X 3200m Dispersion Area Area H is now complete. Area H Annotate Area H on the legend.

21
August 2003 From table 15-1, find the measurement for Area A. 750m Area A = Lightly draw lines perpendicular to sides of the Dispersion Area nearest the firing point. Dispersion Area Distance X 3200m Area H Draw tic marks at 750m.

22
August 2003 From Table 15-1, find the measure- ment for Area B. 750m Area B = Lightly draw lines perpendicular to the remainder of the Dispersion Area. Draw straight lines through the tic marks. Area H Dispersion Area Distance X 3200m

23
August 2003 Draw tic marks at 750m. Area H Dispersion Area Draw straight lines through the tic marks parallel to the sides of the Dispersion Area. Distance X 3200m

24
August 2003 To locate the corner limits of Area A, set the needle of the compass on the corners of the Dispersion Areas and scribe an arc between the limits of Areas A and B. Area H Dispersion Area Distance X 3200m

25
August 2003 To locate the downrange limit of Area B, set the needle of your compass the firing point and scribe an arc through the tic mark between the limits of Area B. Area H Dispersion Area Distance X 3200m

26
August 2003 This completes Areas A and B. Area H Dispersion Area Distance X 3200m

27
August 2003 Annotate on the legend. This completes Areas A and B. Area H Dispersion Area Distance X 3200m Area A Area B Erase any unnecessary lines.

28
August 2003 Area H Dispersion Area Distance X 3200m Area A Area B Annotate on the legend. This completes Areas A and B. Erase any unnecessary lines.

29
August 2003 Area I Area I is the Area immediately in front of certain missile weapon systems designated as the initial zone of impact for “eject-only” firing events. Area I may not be occupied under any condition or deviation.

30
August 2003 The measure- ment for Area I is 800m. From the firing point, scribe an arc between the left and right limits of the Dispersion Area using 800m as the radius. Area H Distance X 3800m Dispersion Area Area A Area B Make a tic mark on the line of fire 800m from the firing point.

31
August 2003 This completes Area I. Annotate Area I on the legend. Area H Dispersion Area Area A Area B Area I Distance X 3800m

32
August 2003 Area F There are three parts to Area F. The Primary Danger Area is a 90° cone with the apex of the cone centered at the rear of the missile launcher having a radius of 50m. Caution Area 1 is an area extending radially from each side of the primary danger Area to the firing line with a radius of 50m. Caution Area 2 is an extension of the primary danger Area with a radius of 75m.

33
August 2003 Locate the launch point and the baseline. 75m From the launch point, extend the missile target line 75m, the measurement of Caution Area 2. From the launch point, place a tic mark at 50m from the baseline. 50m Note: Scale for Area F is 1:500

34
August 2003 75m Scribe an arc from the 50m tic mark to the left and right sides of the baseline. From the launch point, measure 45° from the baseline. 50m 45°

35
August 2003 75m Draw tic marks. Draw straight lines through the tic marks to a length of 75m. 50m 45°

36
August 2003 75m Caution Area 1 Caution Area 2 Primary Danger Area Scribe an arc to form a cone. Annotate the Primary Danger Area. Annotate Caution Area 1. Annotate Caution Area 2. 50m

37
August 2003 Weapon: Basic TOW-HEAT Ammo Type: HEAT Distance X: 5000m Distance D: 3800m Area A: 750m Area B: 750m Area H: 3200m Area I: 800m Area F PDA/CA1/CA2 50m/50m/75m Map Scale: 1:50,000 Map Sheet: Map Series: Map Edition: Date: Name: Legend for the TOW
