Construction

Target detection ranges must be located in areas having good natural vegetation and close to the firing range. (Figure B-5.)

The observation line should be the first area of the target detection range to be built. The location of all downrange panels, sound systems, and foliage depends on the degree of visibility from the defensive position (observation) line. The observation line should be wide enough to accommodate 50 points. The distance between observation points should be no closer than two meters. An observation line of this size can accommodate half of a 200-man unit (50 two-man teams).

NOTE: An initial rehearsal should be conducted for each target detection exercise. More rehearsals are needed only if target men are changed. A presentation refers to each time one exercise is conducted. A rehearsal is counted as a presentation.

The observation fan should cover an area between 30 degrees left of the left flank point of the observation line to 30 degrees right of the right flank point. To provide maximum flexibility in conducting exercises in range determination, the target detection range should be deeper than 500 meters. Installations having limited training space can conduct effective training on ranges at least 300 meters deep.

Both lettered and numbered panels are placed throughout the observation area. The lettered panels serve two purposes: first, they divide the range into sectors defining a firer's area of responsibility; and second, they serve as reference points for marking targets. The numbered panels are used during exercises to locate sound targets. These panels are built so they can be raised or lowered, as needed.

The number of panels needed depends on the size of the range. For a range having a 50-point observation tine and 300 meters deep, about 7 lettered panels and 14 numbered panels will be needed.

Numbered stakes are placed downrange. These stakes are not visible from the observation line since they are used only by instructors and target men in presenting target situations. The number of stakes needed depends on the depth of the range. As a guide, a range 300 meters deep has about 150 stakes. When placing numbered stakes, one technique is to divide the range into three sectors: A, B, and C. This allows for easy reference. Stakes are then numbered beginning at the maximum depth of the range and proceeding forward to the observation line. All stakes in one sector would have the sector letter following the number. For example, if the right sector is designated A, all numbers on stakes in that sector are followed by the letter A. Stakes in the center and left sectors have the letter B or C, respectively, after the number. The location of all panels and stakes must be recorded on the master trial sheets (see Figure B-6).

For proper control of target men, sound equipment is used throughout the observation area. Since problems of adequate sound vary according to location, it is best that a sound survey be conducted of each target detection range before the equipment is installed.

The exact positioning of panels, stakes, and sound equipment is checked from the observation line. Sound equipment should be concealed from the observation line.
