VMC visual meteorological conditions VT variable time WP white phosphorous Section II Terms 140 dBP contour The distance at which the impulse noise produced by the weapon or explosive is 140 decibels peak level. See also hearing hazard zone. ammunition lot A quantity of components, each of which is manufactured by one manufacturer under uniform conditions, and which is expected to function in a uniform manner. The lot is designated and identified by assignment of an ammunition lot number and preparation of an ammunition data card. Angle P The angle beginning at the firing point, located to the left and right of the dispersion area, which defines the area which contains projectiles after making initial contact with the target medium. Angle Q The angle beginning at distance Y, located to the left and right of the dispersion area, which defines the area which contains projectiles after making initial contact with the impact medium. approved hearing protector (or protection) Hearing protector types that are approved for use by the Army and are listed in DA Pam 40–501. Area A The secondary danger area (buffer zone) that laterally parallels the impact area or ricochet area (depending on the weapon system) and contains fragments, debris, and components from frangible or explosive projectiles and warheads functioning on the right or left edge of the impact area or ricochet area. Area B The secondary danger area (buffer zone) on the downrange side of the impact area and Area A which contains fragments, debris, and components from frangible or exploding projectiles and warheads functioning on the far edge of the impact area and Area A. Area C The secondary danger area (buffer zone) on the up range side of the impact area and parallel to Area B which contains fragments, debris, and components from frangible or exploding projectiles and warheads functioning on the near edge of the impact area. Area D The safe area between Areas C and E for indirect, overhead fire of unprotected personnel in training. Area E The danger area between an indirect fire weapon system and Area D. This area is endangered by muzzle debris, overpressure, blast, and hazardous impulse noise. Personnel in service batteries firing from approved tactical configura- tions may occupy Area E. Area F The danger area to the rear of a weapon system that is endangered by back-blast debris, overpressure, blast, and hazardous impulse noise. 227 DA PAM 385–63 • 16 April 2014
