explosive or chemical, biological, radiological, nuclear, and high yield explosives (cbrne) that is thrown by hand, dropped from an aircraft, or projected by some slow means. (eod refers to it in relation to aircraft or ides).
cylindrical surface that bears the weight of the projectile in the bore, it is the measuring point for the diameter of the projectile, and can extend the full length of the projectile.
a projectile fired, or intended to be fired from a small arm.
diameter of a projectile at the bourrelet, or the inner measurement of the bore on a gun.
an assemblage of the components required to function a weapon once, (ex. gun ammunition which contains in a unit assembly all of the components required to function the gun once, and which is loaded into the gun in one operation.)
a given quantity of explosives, by itself or contained within a bomb, projectile, mine, or used as a propellant for a bullet or projectile.
a striker/firing pin/detonator that are held under tension by a releasing mechanism such as a safety pin on a grenade.
very rapid combustion, sometimes accompanied by flames and sparks (ex. the burning of black powder).
an explosion, a chemical reaction/burn that surpasses the speed of sound creating the detonation velocity which ruptures the outer container of explosive, if any.
technique to cause the main charge to low order, or during ides, creates a break in the firing train. low order is when ... High order is when...
explosion munition which has not been armed as intended or which has failed to explode after being armed.
all munitions that contain explosives, pyrotechnics, or cbrne that cause death/injury to personnel or damage to material.
explosive ordnance disposal procedure
action taken by eod to render safe, disassemble, neutralize or dispose of ordnance, in which the eod soldier observes the safeties first.
insures the steady flight of the ordnance with the use of fins.
term used with the ordnance that is designed to break apart or fragment during detonation (ex. fragmentation of a grenades serrated body).
initiator for ordnance and the attacking point for most render safe procedures (rep)
allows the fuze to be attached to various sizes of ordnance, (155mm to 105mm with same fuze). on a bomb, it may be connected to the parachute to assist in chute deployment.
the ability of a fuze to be initiated by grazing the surface at a glancing angle.
small fragmentation (defensive) or last (offensive) ordnance originally designed to be thrown by hand, but now also designed to be projected from rifles, special launchers and dispensing munitions.
the flow of current from an item in an electrical circuit to the ground. a physical connection with the earth to equalize potential and to discharge stray components (ex. fuzes explosive trains) or cause an explosive tool to discharge.
an explosive that will normally high order not low order.
a striker/firing pin/detonator which remains cocked and under tension after the releasing mechanism is removed (ex. grenade with a hung striker) due to an obstruction such as sand or rust.
substance that absorbs and holds water, particularly from the air (ex. desiccant bags you find in pills and beef jerky).
improvised explosive device
those devices placed or fabricated in an improvised manner incorporating destructive, lethal, noxious, pyrotechnic or incendiary chemicals, designed to destroy, disfigure, distract or harass.
failure of ordnance to function in a normal or expected manner.
an explosive or other material, normally encased, designed to destroy or damage ground vehicles, boats, aircraft or designed to wound, kill or otherwise incapacitate personnel. it may be detonated by the actions of its victim, passage of time or by controlled means.
failure to fire or explode properly. failure of a primer or propelling charge to function, wholly or in part.
in a restricted sense, ordnance items such as bombs, rockets, projectiles, an grenades.
identifying name for ordnance items (ex cartridge, 81mm, m43a1)
foremost point of a bomb/projectile/missile, which is tapered or rounded to provide aerodynamic and ballistic stability.
the pinched or constricted area of a rocket motor or engine where the flame and gasses are released.
curved or tapered front portion of a projectile.
explosives , ncb munitions, pyrotechnics, bombs, guns, and ammunition.
an object projected by an applied force, within eod it is generally applied to artillery rounds/recoilless rifle rounds.
projectile, high explosive plastic
thin cased projectile that is designed to defeat armored objects. they are referred to as hep, squash head, or bunker buster rounds.
render safe procedure (rep)
the portion of the eod procedure which is designed to prevent the detonation or functioning of the explosive ordnance. it is normally accomplished with the aid of special tools and techniques.
the spiraling grooves in the gun tube that create the spinning of the rounds.
unmanned, self-propelled ordnance with or without a warhead that when launched its flight cannot be controlled.
soft metal band on the base that centers the round in the bore, creates the spin from filing, and prevents the escape of a gases.
a carrier for a sub-caliber projectile so that it ma fit into a larger bore gun, the carrier is usually discarded after it is fired from the gun.
the determination by eod that an item is set or reset so as not to detonate or function accidentally.
safe and arming device
a mechanism whose primary purpose is to prevent an unintended functioning of the main charge prior to completion of the arming delay and, in turn allows the explosive train of the ammunition to function after arming.
a device that prevents ordnance from being fired accidentally. prevention of conditions which can cause injury or death to personnel or damage or loss of equipment or property.
gun tube that is smooth inside. it does not impart spin to the round (ex abrams tank 120mm main-gun, shotguns and some mortar tubes).
the spinning of a projectile caused by the rifling in a barrel, keeping it straight in flight, not tumbling.
distance from the base of a shaped charge to the target that gives the jet time to form for penetration.
bar, timber, or metal beam designed to take strain (ex portion of the bomb that contains the lifting lugs and supports the weight of the bomb)
