contaminated area Any area where there are known or suspected unexploded munitions (dud ammunition or explosives) regardless of type. control tower A structure usually situated behind the firing line or position from which range operations of a training event is controlled. cookoff A functioning of any or all of explosive components due to high temperatures within a weapon system. crew-served weapon system Any weapon system requiring two or more personnel to fire the system. cross-sectional terrain profile A profile of the SDZ being considered for deviation at a point laterally downrange where a hill mass is expected to attenuate projectiles and/or hazardous fragments. decibel peak level A logarithmic method of expressing the peak pressure caused by an explosion. dedicated impact area See impact area. deviation A departure from the requirements of this pamphlet and the policy in AR 385–63/ MCO 3570.1C. direct fire Fire delivered on a target when the weapon system is laid by sighting directly on the target using the weapon system sighting equipment. dispersion area The area within the SDZ located between the GTL and the ricochet area. This area accounts for human error, gun or cannon tube wear, propellant temperature, and so forth. Distance D Distance along specific angle, measured from the weapon target line, at the firing position down range for selected direct fire weapons. Distance D defines maximum projectile distance along this line. Distance L The distance down range from the launch point where the launch dispersion angle intersects the flight corridor boundaries for the PATRIOT missile. Distance W The maximum lateral distance a projectile will ricochet after impacting within the dispersion area. Distance W defines the maximum lateral edge of the ricochet area. Distance X The maximum distance a projectile (to include guided missiles and rockets) will travel when fired or launched at a given quadrant elevation with a given charge or propulsion system. Distance Y The maximum distance downrange at which a lateral ricochet is expected to occur when a projectile is fired at a given quadrant elevation. double hearing protector (or protection) Wearing earplugs in combination with noise muffs or noise attenuating helmets. Impulse levels can be so high that single hearing protection does not adequately protect hearing. downrange A descriptive term used to address the orientation of personnel, materiel, or property relative to the direction or path of 229 DA PAM 385–63 • 16 April 2014
