He may recommend the best method of attack based on the size, type, and posture of the target. For common target type equivalents, see Table E-2 .
Targets vary considerably in composition, degree of protection, shape, mobility, and recuperability.
Information in weapons effects manuals is based on the assumption that personnel are wearing helmets and winter uniforms and that those in foxholes are in a crouching position. When describing a given target's posture, consideration must be given to the protection afforded by the terrain. This change is called posture sequencing. This characteristic causes considerable degradation of effects as additional volleys are fired and is the reason for the emphasis on surprise or massed fires. A target must be analyzed to determine its weak points.
