  1. bomb
    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).
  2. bourrelet
    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.
  3. bullet
    a projectile fired, or intended to be fired from a small arm.
  4. caliber
    diameter of a projectile at the  bourrelet, or the inner measurement of the bore on a gun.
  5. cartridge
    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.)
  6. charge
    a given quantity of explosives, by itself or contained within a bomb, projectile, mine, or used as a propellant for a bullet or projectile.
  7. cocked striker
    a striker/firing pin/detonator that are held under tension by a releasing mechanism such as a safety pin on a grenade.
  8. deflagration
    very rapid combustion, sometimes accompanied by flames and sparks (ex. the burning of black powder).
  9. detonation
    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.
  10. disruption
    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...
  11. dud
    explosion munition which has not been armed as intended or which has failed to explode after being armed.
  12. explosive ordnance
    all munitions that contain explosives, pyrotechnics, or cbrne that cause death/injury to personnel or damage to material.
  13. 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.
  14. fin stabilization
    insures the steady flight of the ordnance with the use of fins.
  15. fragmentation
    term used with the ordnance that is designed to break apart or fragment during detonation (ex. fragmentation of a grenades serrated body).
  16. fuze
    initiator for ordnance and the attacking point for most render safe procedures (rep)
  17. fuze adapter
    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.
  18. graze sensitive
    the ability of a fuze to be initiated by grazing the surface at a glancing angle.
  19. grenade
    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.
  20. ground
    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.
  21. high explosive
    an explosive that will normally high order not low order.
  22. hung striker
    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.
  23. hygroscopic
    substance that absorbs and holds water, particularly from the air (ex. desiccant bags you find in pills and beef jerky).
  24. 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.
  25. malfunction
    failure of ordnance to function in a normal or expected manner.
  26. mine
    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.
  27. misfire
    failure to fire or explode properly. failure of a primer or propelling charge to function, wholly or in part.
  28. munitions
    in a restricted sense, ordnance items such as bombs, rockets, projectiles, an grenades.
  29. nomenclature
    identifying name for ordnance items (ex cartridge, 81mm, m43a1)
  30. nose
    foremost point of a bomb/projectile/missile, which is tapered or rounded to provide aerodynamic and ballistic stability.
  31. nozzle/venturi
    the pinched or constricted area of a rocket motor or engine where the flame and gasses are released.
  32. ogive
    curved or tapered front portion of a projectile.
  33. ordnance
    explosives , ncb munitions, pyrotechnics, bombs, guns, and ammunition.
  34. projectile
    an object projected by an applied force, within eod it is generally applied to artillery rounds/recoilless rifle rounds.
  35. 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.
  36. 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.
  37. rifling
    the spiraling grooves in the gun tube that create the spinning of the rounds.
  38. rocket
    unmanned, self-propelled ordnance with or without a warhead that when launched its flight cannot be controlled.
  39. rotating band
    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.
  40. sabot
    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.
  41. safe
    the determination by eod that an item is set or reset so as not to detonate or function accidentally.
  42. 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.
  43. safety
    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.
  44. smooth bore
    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).
  45. spin stabalization
    the spinning of a projectile caused by the rifling in a barrel, keeping it straight in flight, not tumbling.
  46. standoff
    distance from the base of a shaped charge to the target that gives the jet time to form for penetration.
  47. strong back
    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)
