Which mission involves using both direct and indirect fire against an enemy?

The mission that involves using both direct and indirect fire against an enemy is the option that focuses on attacking the enemy while simultaneously utilizing different forms of firepower. In military operations, an attack by fire mission allows forces to engage the enemy from a distance, using indirect fire (such as artillery or mortar fire) to suppress them, while also being capable of direct fire (such as rifle or machine gun engagement) to maintain pressure and control over the battlefield.

This dual capability enhances tactical flexibility, enabling forces to adapt to various battlefield conditions and the enemy's responses. The effectiveness of using both types of fire supports a coordinated effort to neutralize enemy positions and allows for more dynamic engagement strategies.

Other missions, while important, are more specialized and do not necessarily involve the integration of both direct and indirect fire. For instance, a control mission focuses on maintaining area dominance, a breach mission is primarily about creating openings in enemy defenses, and counterreconnaissance aims to thwart enemy surveillance rather than engaging in a direct or indirect attack.
