What is a type of defensive operation that involves organized movement away from the enemy?

A retrograde operation is a type of defensive maneuver that is characterized by an organized movement away from the enemy. It primarily serves the purpose of preserving forces, repositioning troops, and sometimes setting up for a counter-offensive. This operation can take various forms, such as withdrawals, delays, or retirements, but its overarching concept revolves around maintaining control over how and when forces disengage from combat.

In a retrograde, troops utilize tactics that may involve falling back, creating a buffer, and allowing the enemy to advance into predetermined positions where they can be effectively engaged or disrupted. This strategic retreat can also help in conserving resources and minimizing casualties while repositioning for future engagements.

The other options do not convey the same organized movement away from the enemy or serve to either maintain position or actively engage rather than retreat.
