What feature allows for direct fire capabilities with the M777A2?

The ability to engage at lower elevations is a crucial feature that allows the M777A2 Howitzer to perform direct fire operations effectively. When engaging targets at lower elevations, the howitzer can achieve a flatter trajectory that is conducive to direct fire, allowing for improved accuracy against targets within its range. This capability broadens the operational versatility of the M777A2, permitting it to support ground troops in close quarters or engage enemy forces without the need for indirect fire angles that are typically used for higher elevation shots.

Combined with its other advanced features, the ability to fire directly essentially increases the responsiveness of the artillery unit and provides support in dynamic battlefield scenarios where indirect firing might be less practical or too time-consuming. While high muzzle velocity, laser guidance, and high-explosive projectiles provide significant advantages, it is the capacity to engage at lower elevations that enables the M777A2 to perform direct fire operations effectively, making it a vital answer to the question.
