Which area includes efforts to prevent enemy forces from being effectively committed?

The deep area encompasses operations that focus on targeting enemy forces before they can effectively deploy or engage in combat. This area is vital for disrupting the enemy's planning and movement, thereby hindering their operational capabilities. By conducting actions in this zone, military forces aim to create a strategic advantage, as they can engage the enemy's resources, command structures, and supply lines at a distance.

The purpose of operating in the deep area is to shape the battlefield and reduce the effectiveness of the enemy's immediate response or engagement, thereby allowing friendly forces to maneuver with less opposition. This can involve a variety of tactics such as airstrikes, long-range artillery, and reconnaissance missions that gather intelligence to inform decisions and target enemy capabilities.

In contrast, the other areas—close, support, and consolidation—do not primarily focus on the proactive disruption of enemy forces before they engage. The close area is more about direct engagement with enemy combatants, the support area pertains to logistical and support operations for forces in contact, and the consolidation area deals with post-combat operations and securing gains. Therefore, the emphasis on preventing enemy forces from being effectively committed is distinctly aligned with the mission and objectives of the deep area.
