ParamilitaryA paramilitary is an organization whose structure, tactics, training, subculture, and (often) function are similar to those of a professional military, but which is not part of a country's official or legitimate armed forces. Paramilitary units carry out duties that a country's military or police forces are unable or unwilling to handle. Other organizations may be considered paramilitaries by structure alone, despite being unarmed or lacking a combat role.
ProjectileA projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow, stone released from catapult). In ballistics mathematical equations of motion are used to analyze projectile trajectories through launch, flight, and impact.
Close-quarters combatClose-quarters combat (CQC) or close-quarters battle (CQB) is a close combat situation between multiple combatants involving ranged (typically firearm-based) or melee combat. It can occur between military units, law enforcement and criminal elements, and in other similar situations. In modern warfare, close-quarters combat usually consists of an engagement between two forces (typically "attackers" and "defenders") of varying size with small arms within a distance of up to 100 meters (110 yards), ranging from close-proximity shootouts to hand-to-hand combat.
Law enforcementLaw enforcement is the activity of some members of government who act in an organized manner to enforce the law by discovering, deterring, rehabilitating, or punishing people who violate the rules and norms governing that society. The term encompasses police, courts, and corrections. These three components may operate independently of each other or collectively, through the use of record sharing and mutual cooperation. Throughout the world, law enforcement are also associated with protecting the public, life, property, and keeping the peace in society.
Militarization of policeThe militarization of police (paramilitarization of police in some media) is the use of military equipment and tactics by law enforcement officers. This includes the use of armored personnel carriers (APCs), assault rifles, submachine guns, flashbang grenades, sniper rifles, and SWAT (special weapons and tactics) teams. The militarization of law enforcement is also associated with intelligence agency–style information gathering aimed at the public and political activists and with a more aggressive style of law enforcement.
Cartridge (firearms)A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, the correct usage only refers to the projectile.
