A shell, in a modern military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling.
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems.
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a receiver) and the electronics necessary for it to find and track its target autonomously.
An anti-radiation missile (ARM) is a missile designed to detect and home in on an enemy radio emission source.
A wire-guided missile is a missile that is guided by signals sent to it via thin wires connected between the missile and its launch platform using command guidance. As the missile flies, the wires are reeled out behind it.
In military terminology, a rocket is a self-propelled, unguided or guided, weapon-system powered by a rocket engine
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target.
A chemical weapon agent (CWA), or chemical warfare agent, is a chemical substance whose toxic properties are meant to kill, injure or incapacitate human beings.
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than 5,500 kilometres (3,400 mi), primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads).
