What type of round is the M889?

The M889 round is classified as a high explosive round. High explosive rounds are designed to create a significant blast effect upon detonation, which is crucial for engaging enemy personnel and material effectively on the battlefield. The M889 specifically contains a composition that allows it to generate a powerful explosion, making it suitable for offensive operations where the effective application of firepower is required to destroy or neutralize targets.

In contrast, training rounds are typically designed to simulate firing without the destructive capability of high explosive rounds, illumination rounds are used to light up an area for visibility, and smoke rounds are meant to create a smoke screen for concealment or signaling purposes. Each type of round has a distinct purpose and application in military operations, which is important to understand when selecting munitions for specific missions.
