How can the M777A2 be deployed rapidly?

The M777A2 howitzer is designed for rapid deployment primarily because of its lightweight construction, which allows it to be airlifted by helicopter or towed by various vehicles, facilitating quick movement to necessary firing positions. This versatility is crucial in military operations, as it enables forces to position artillery in locations that may be otherwise difficult to access quickly.

The M777A2 weighs significantly less than previous artillery systems, making it feasible for transport by air and ground, which enhances operational flexibility. The ability to use helicopters for airlifting means that the howitzer can be rapidly deployed to remote or difficult terrains that traditional ground transport may not reach efficiently or quickly enough.

In contrast, while other options may suggest methods of transport or deployment, they do not factor in the unique lightweight capability of the M777A2 which is central to its rapid deployment. Thus, the emphasis on its lightweight and the ability to be towed or airlifted underscores why this is the correct understanding of how the M777A2 can be rapidly deployed.
