What type of ammunition does the M777A2 typically use?

The M777A2 Howitzer typically uses conventional artillery shells, making this the correct response. This type of ammunition includes high-explosive shells, illuminating rounds, and smoke shells, all designed to be fired from the howitzer to achieve various battlefield objectives. Conventional artillery shells provide versatility, allowing for both explosive impact and other mission-specific functionalities such as signaling and obscuring enemy vision.

In contrast, laser-guided missiles are not standard for an artillery piece like the M777A2, as they are more commonly associated with precision-guided munitions used in air-to-ground or ground-to-air roles. Ballistic missiles, which are designed for long-range strikes with typically larger payloads, do not fit the operational profile of the M777A2 either, as it primarily serves in conventional artillery roles. Additionally, small arms ammunition is used in personal firearms and is not compatible with the artillery systems designed for heavier, larger-caliber munitions. Thus, conventional artillery shells are the logical choice for use with the M777A2.
