A "force multiplier" can be defined as a system that enhances unit effectiveness, which is why this choice is correct. The concept refers to tools, strategies, or capabilities that significantly increase the effectiveness, impact, and efficiency of military forces without a corresponding increase in personnel. This can include advanced technology, training, leadership, and tactics that allow a smaller force to achieve results that typically require a larger force.

For instance, the introduction of sophisticated communication systems or unmanned systems can provide real-time intelligence and enhance coordination among units, ultimately leading to superior operational performance. By improving the overall effectiveness of a unit, these systems can help achieve mission objectives more efficiently and with greater success.

The other options do not capture the essence of what a force multiplier is meant to achieve. A simple task doesn't enhance effectiveness; it merely tasks personnel. Complicated command structures can create confusion and inefficiency rather than enhance effectiveness. While tools for reducing manpower needs can be beneficial, they aren’t necessarily force multipliers unless they also enhance overall effectiveness in operations.
