What are the four types of rounds?

The four types of rounds are Ball, Blank, Tracer, and Dummy.

Ball rounds are standard live ammunition used for regular shooting exercises and combat situations. They are designed for accuracy and terminal effectiveness during engagement.

Blank rounds are used for training purposes or simulations, allowing the shooter to practice the mechanics and actions of firing a weapon without expending live ammunition. They generate a muzzle flash and sound but do not have a projectile, making them ideal for practice scenarios without the risk of live fire incidents.

Tracer rounds contain a pyrotechnic charge that ignites and burns brightly, providing a visual cue to the shooter about the trajectory of their shots. This helps in adjusting aim and enhances the coordination of fire during combat.

Dummy rounds are non-firing cartridges that have no propellant or primer, often used for training to practice loading and unloading weapons without the risk associated with live rounds. They allow trainees to familiarize themselves with weapon systems and serve as a safe means to handle and manipulate firearms.

Each of these rounds serves a specific purpose, contributing to effective training and operational readiness for Marines.
