What tactical concept is utilized primarily for envelopment strategies?

The tactical concept primarily utilized for envelopment strategies is flanking movement. Envelopment involves maneuvering around the enemy's flanks to attack from the sides or rear, taking advantage of their weaker positions and potentially leading to a complete encirclement. This tactic disorients the enemy and can create opportunities for more decisive engagements.

Flanking movement specifically allows forces to bypass enemy defenses, engaging them from unexpected directions, which can disrupt their command and control while maximizing the attacking force's effectiveness. It often leads to confusion and disarray within the enemy ranks, making it a critical tactic for achieving tactical surprise and gaining the advantage in battle.

The other options focus on different tactics that, while useful in various scenarios, do not specifically pertain to the concept of enveloping the enemy as effectively as flanking movement does.
