Which of the following are forms of maneuver in military operations?

Maneuver in military operations refers to the movement of forces to gain an advantage over the enemy. It involves various tactical approaches designed to outmaneuver the opponent, disrupt their operations, and achieve favorable positioning.

The correct answer highlights two key tactical maneuvers: flank attack and infiltration. A flank attack involves striking the enemy from the side, taking advantage of their less protected positions, and creating opportunities for a decisive engagement. Infiltration, on the other hand, refers to secretive movement into enemy territory, often to gather intelligence or execute a surprise attack from within. Both concepts are integral to achieving tactical surprise and exploiting vulnerabilities in enemy defenses, making them essential elements of maneuver warfare.

The other choices lack this focus on tactical movement. Defense and retreat refer to more static elements of military operations, focusing on holding positions rather than actively maneuvering against the enemy. Defense and envelopment, while they do involve tactical maneuvering, suggest a more static approach where forces defend while anticipating the enemy's movement, rather than actively engaging through offensive maneuvers. Liaison and reconnaissance pertain more to coordination and information gathering than the direct engagement tactics that maneuver warfare emphasizes. Thus, the selection of flank attack and infiltration captures the essence of dynamic and strategic movement
