5.56 mm Ammunition

Standard Types for Small Arms

5.56 × 45 mm ammunition is one of the most widely used small‑arms cartridges in service with armed forces worldwide. Multiple types are produced to support different operational and training needs:

• Ball – standard combat rounds for general purpose engagements.

• Tracer – equipped with a pyrotechnic compound to produce a visible trajectory for fire adjustment and target indication.

• Blank – cartridges without a projectile, used for training and simulation exercises.

• Dummy / Non‑Bullet – inert rounds with no propellant, used safely for handling and loading drills.

Designations such as M193 and related variants are part of standardized nomenclature used in military inventories to distinguish between these functional types.

Each type supports a specific role, making 5.56 mm ammunition a flexible and essential component of modern small‑arms systems.
