What is one feature that enhances the portability of the M777A2?

The M777A2 howitzer is designed with lightweight construction materials as a key feature to enhance its portability. The incorporation of advanced materials, such as titanium and aluminum alloys, significantly reduces the overall weight of the howitzer compared to traditional artillery. This reduction in weight allows for easier transportation and maneuverability on the battlefield, enabling it to be towed by helicopters or lightweight vehicles and moved quickly to different positions as needed. The focus on portability is crucial for modern artillery units, which must be able to reposition effectively and respond swiftly to changing combat conditions.

Other features, while valuable in their own right, do not specifically address the need for lighter weight and enhanced mobility that is critical for artillery effectiveness in various operational contexts.
