Which maneuver involves an attacking force seizing objectives behind enemy defenses?

The maneuver that entails an attacking force seizing objectives behind enemy defenses is known as a Single Envelopment. This strategy is characterized by a force maneuvering around the enemy to attack their rear or flank, disrupting their operations and supply routes while achieving strategic objectives that may not be easily accessible from the front. By executing a Single Envelopment, the attacking force can exploit vulnerabilities in the enemy's defense, create confusion, and potentially encircle the maneuvering enemy, leading to decisive victory.

In contrast, a Turning Movement aims to bypass the enemy's front to strike at their command or logistics, but it does not specifically involve seizing objectives. A Linear Assault involves a frontal attack against a position, which is more direct and does not involve the complexities of maneuvering to the rear. A Frontal Maneuver focuses on attacking the enemy head-on rather than outflanking them, which does not exploit the strategic advantage of moving behind enemy lines. Therefore, the Single Envelopment distinctly stands out as the maneuver that directly refers to seizing objectives located behind the enemy's defenses.
