Final answer:
A training cartridge is a simulation tool used in law enforcement or military training that looks like a live cartridge but contains no explosive materials, probes, or wires.
Step-by-step explanation:
The term "training cartridge" typically refers to a device used in law enforcement or military training that simulates the behavior of a live cartridge but does not contain any live propellant or explosive materials such as nitrogen.
These cartridges often do not include the elements found in a live round, such as probes or wires.
Despite lacking these components, a training cartridge might still appear on the Cartridge, Impulse Disposable (CID) as a live cartridge due to its design and functionality meant to replicate a real cartridge for training purposes.
