Which of the following is NOT a form of maneuver in infantry tactics?

Withdrawal is considered a defensive action rather than a form of maneuver in infantry tactics. In the context of military operations, flanking, turning movement, and envelopment all involve actively positioning forces to gain an advantage over the enemy, typically by attacking from the side or rear to disrupt their formations and command structure.

Flanking is about maneuvering around the sides of an enemy position, while turning movement involves moving around the enemy to strike at their rear or supply lines. Envelopment goes further, encircling the enemy to cut off their escape and resources. On the other hand, withdrawal focuses on retreating from a position, often for strategic purposes, but it does not engage with the enemy in a manner that seeks to outmaneuver them. Thus, while it is a critical tactic in certain scenarios, it does not fit into the category of offensive forms of maneuver.
