SDZ Construction:
TOW
Inter-service Resident Range Safety Course
(Intermediate)
TOW missiles engage and destroy
enemy armored vehicles, primarily tanks.
August 2003
The basic TOW Weapon System
was fielded in 1970.
August 2003
TOW 2 Missile has extended probe. It was
first introduced with ITOW.
August 2003
BGM-71A Basic TOW: The original TOW
missile had a diameter of 5” and a range of 3000
meters.
August 2003
BGM-71C Improved TOW (ITOW): This missile
includes an extended probe for greater standoff
and penetration.
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.
August 2003
BGM-71E TOW 2A: The TOW2A has the
capability to defeat reactive armor.
August 2003
BGM-71F TOW 2B: The TOW 2B Missile
incorporates new fly-over, shoot-down technology.

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.

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.
