Classification
By user
- what person or unit uses the weapon
• Personal weapons (or small arms) - designed to be used by a single person.
• Hunting weapon - primarily for hunting game animals for food or sport
• Infantry support weapons - larger than personal weapons, requiring two or more to operate correctly.
• Fortification weapons - mounted in a permanent installation, or used primarily within a fortification.
• Mountain weapons - for use by mountain forces or those operating in difficult terrain.
• Vehicle weapons - to be mounted on any type of military vehicle.
• Railway weapons - designed to be mounted on railway cars, including armored trains.
• Aircraft weapons - carried on and used by some type of aircraft, helicopter, or other aerial vehicle.
• Naval weapons - mounted on ships and submarines.
• Space weapons - are designed to be used in or launched from space.
By function
- the construction of the weapon and principle of operation
• Antimatter weapons (theoretical) would combine matter and antimatter to cause a powerful explosion.
• Archery weapons operate by using a tensioned string to launch a projectile.
• Artillery are capable of launching heavy projectiles over long distances.
• Biological weapons spread biological agents, causing disease or infection.
• Chemical weapons, poisoning and causing reactions.
• Energy weapons rely on concentrating forms of energy to attack, such as lasers or sonic attack.
• Explosive weapons use a physical explosion to create blast concussion or spread shrapnel.
• Firearms use a chemical charge to launch projectiles.
• Improvised weapons are common objects, reused as weapons.
• Incendiary weapons cause damage by fire.
• Non-lethal weapons are designed to subdue without killing.
• Magnetic weapons use magnetic fields to propel projectiles, or to focus particle beams.
• Mêlée weapons operate as physical extensions of the user's body and directly impact their target.
• Missiles are rockets which are guided to their target after launch. (Also a general term for projectile weapons).
• Nuclear weapons use radioactive materials to create nuclear fission and/or nuclear fusion detonations.
• Primitive weapons make little or no use of technological or industrial elements.
• Ranged weapons (unlike Mêlée weapons), target a distant object or person.
• Rockets use chemical propellant to accelerate a projectile
• Suicide weapons exploit the willingness of their operator to not survive the attack.
• Trojan weapons appear on face value to be gifts, though the intent is to in some way to harm the recipient.
By target
- the type of target the weapon is designed to attack
• Anti-aircraft weapons target missiles and aerial vehicles in flight.
• Anti-fortification weapons are designed to target enemy installations.
• Anti-personnel weapons are designed to attack people, either individually or in numbers.
• Anti-radiation weapons target sources of electronic radiation, particularly radar emitters.
• Anti-satellite weapons target orbiting satellites.
• Anti-ship weapons target ships and vessels on water.
• Anti-submarine weapons target submarines and other underwater targets.
• Anti-tank weapons are designed to defeat armored targets.
• Area denial weapons target territory, making it unsafe or unsuitable for enemy use or travel.
• Hunting weapons are civilian weapons used to hunt animals.
• Infantry support weapons are designed to attack various threats to infantry units.
