APPENDIX E

TARGET ANALYSIS AND MUNITIONS EFFECTS

This appendix implements QSTAG 224.

E-1. OBSERVER RESPONSIBILITIES

As the eyes of the artillery and mortars, the observer has two major responsibilities regardmg target analysis and munitions effects:

E-2. TARGET DESCRIPTION

The following is a brief description of considerations in describing a target properly to the FDC. It is based on weapons effects analysis in TACFIRE. For common target type equivalents, see Table E-2.

a. Target Characteristics.

b. Target Location. The proximity of the target to friendly troops and the accuracy of the target location must be weighed. The importance of certain targets that are not accurately located may justify the fire of several units to ensure coverage. Close-in direct support fire requirements may dictate the use of a specific type or caliber of weapon or a specific type of munition.

c. Terrain. The terrain in the target area has a direct effect on the vulnerability of a target. Rugged terrain affords considerable natural cover and makes target location difficult. Certain terrain provides a complete defile from some angles of fire but not from others. This influences the type of weapon and munition to be used. The nature of the vegetation in the target area should be considered in recommending ammunition.

d. Weather. Weather is of little consequence in evaluating a target to be attacked with HE/Q. Precipitation and wind are of particular importance in eva]uating a target to be attacked with ICM, smoke, FASCAM, or illuminating projectiles. Low clouds, thick fog surface water, and rain degrade the effectiveness of VT fuzes M513 and M514. Fuzes M728 and M732 are not affected.

e. Commander's Criteria. All phases of target analysis are conducted within constraints established by the commander. On the basis of ammunition constraints, a commander will stipulate the type of effects he desires against specific target categories. The three target effects categories are discussed below.

E-3. MOST SUITABLE AMMUNITION

Once an observer has decided to attack a target, he must select a weapon-ammunition combination that can achieve the desired effect with a minimumn expenditure of available ammunition stocks. To do this, the observer must know the characteristics, capabilities, and vulnerabilities of all fire support assets.

a. Ammunition Type and Quantity. The nature of the target and its surroundings and the desired effects dictate the type and amount of ammunition to be used. For a detailed discussion of ammunition and fuzes, refer to Table E-3. The ammunition resupply system may sometimes rule out an optimum ammunition selection. For example, extensive smoke fires may be needed to screen maneuver nlovement but such fires would probably impose a considerable resupply problem on the parent organization. Some types of fires require greater ammunition expenditures thm others. Suppression and neutralization fires usually consume less ammunition than destruction fires.

b. Troop Safety. Troop safety is a major concern when considering the weapon and ammunition selection for firing close-in targets. The observer ensures that fires do not endanger friendly troops, equipment, and facilities.

c. Residual Effects in Target Area. Residual effects from special ammunition influence the occupation of an area. Use of FASCAM may change the direction of movement of supported elements. If supported troops are to occupy an area immediately following attack by certain munitions, conditions may be hazardous. Weather changes may alter choices of certain munitions; for example, smoke, illumination, and special ammunition. The incendiary effects of munitions may make areas untenable for supported forces. These effects also can deny the enemy use of selected terrain.

d. Effectiveness. When properly delivered against appropriate targets, artillery and mortar fire support can be the decisive factor in a battle. The observer must ensure that maximum effectiveness is attained from every mission. To match a munition to a target, the observer must know what damage a munition can produce and the damage required to defeat the target. The lethality of a munition must be matched to the specific vulnerability of the target. Thus, the observer must understand the damage potential of blast, cratering, fragmentation, incendiary, and penetration effects from specific munitions.

E-4. METHOD OF ATTACK

The final step in target analysis is the selection of a method of attack. The observer must select a method of attack that ensures target area coverage and desired target effects. To determine an optimum method of attack, the FDO must consider aiming points and density and duration of fires.

a. Aiming Points. Normally, the size of the area to be attacked is determined by the size of the target or the size of the area in which the target is known or suspected to be located. A single aiming point located on the center of the target is used to attack small targets. In attacking large targets, multiple aiming points must be designated to distribute the fires and ensure adequate coverage. The BCS determines aiming points for each howitzer. Chapter 6 gives procedures for establishing multiple aiming points.

b. Density and Duration of Fires. Intense fires of short duration generally produce the best target effect. However, the tactical situation may require fires to be continued over a long period of time. Some examples are interdiction fires, screening smoke fires, continuous illumination, and suppressive fires supporting a maneuver final assault on an objective.

NOTES:

1. Regardless of type, targets with an estimated target radius greater than 150 meters usually require massing for effective attack.

2. The first objective in firing on moving vehicles is to stop the movement. For this purpose a bracket is established. Speed of adjustment is essential. If possible, the column should be stopped at a point where vehicles cannot change their route and where one stalled vehicle will cause others to stop. Vehicles moving on a road can be altacked by adjusting on a point on the road and then timing the rounds fired so that they arrive at that point when the vehicle is passing it. A firing unit or several units, if available, may fire at different points on the road simultaneously.
