Knowledge of firearms is a science that looks at the movement of the fiery projectile and the empty case as well as the result of this movement such as the physical effects of the weapon inside and outside after the launch, and the associated effects on the body of the patient within the scientific basics and platforms. This science has evolved between the years 1930 -1935 at the hands of the German scholars Haas and Haschar after having conducted multiple tests on a large number of firearms, depending for this purpose on the philosophical theory  that (everything material in nature is equal to the same or a photocopy of it), which means that each firearm has special imprint and it cannot be similar to any other weapon even if it is of the same type and caliber and for which the individual marks distinguishing the arms are put and what applies to arms pipe in this regard, as we have said, applies to all parts of the weapon that interact with the case such as shooting needle, shocker and dragger ... etc

Because of this uniqueness in different individual marks of the weapon one from another, this science has received special attention of researchers working in the field of criminal science, as they had found it having great benefits in exposing the crimes committed by firearm. To serve this goal, they have put a number of advanced devices and microscopes.

What applies to firearms in terms of principle and in terms of the fact that everything physical in nature is equal with the same or a picture of it, will apply to machines such as the effects of equipments, car wheels, footprints and the effects of teeth etc., such physical effects that can be left by the perpetrator behind him at the scene.

Specialties and Tasks of Arms and Machinery Department

• Study of firearms to make sure of its kind and caliber, number and whether it is suitable for use or not and study about the munitions of all kinds.
• Ensure whether there were effects of firearms or not.
• Examine ballistics and empty cases or their parts to make sure of their types and calibers, as well as investigation of identity of the weapon used via their individual distinguishing marks.
• Identify the distances of shoots on various infected objects.
• Ensure whether the incident was a suicide or result of tampering or mistake or was it done with the purpose of self-mutilation or not or whether it was killing incident.
• Review the injuries at incident place to make sure whether they were result of projectiles, by specifying their type, caliber and the shooting distance.
• Inspection of the weapons and ammunitions reaching to the country by issuing non-objection certificates.
• Check the glass panels to explain the direction that had been exposed to break by the projectile or by any other tool.
• Check the pistol shots for fixing building materials and decoration works.
• Inspection of materials to indicate whether they are composed of explosive gunpowder or not
• Inspection of thefts incidents of different types, as well as checking doors and locks to get to know the way and style by which they were opened, further specifying the identity and type of the machine used at the incident.
• Find and secure the footprints and match them with the boots of any person suspected of committing the incident.
• Find and secure the effects of wheels of all types of vehicles at the scene and match them with wheels of any vehicle or car suspected of committing the accident.
• Ensure whether the car accident was a fabricated one or a real accident.
• Find out if there was any collisions between cars or not by nature of the damages occurred as well as the effects of exchanging paint.
