What does "retrograde" entail in a tactical situation?

In a tactical situation, "retrograde" refers to a process of withdrawing forces while simultaneously executing defensive measures. This term encompasses the strategic means of pulling back troops or resources while maintaining a defensive posture to cover the withdrawal and protect against enemy advances.

The goal of a retrograde maneuver is to maintain combat effectiveness and ensure that the retreat can be conducted in an organized manner, often while engaging the enemy to slow down their advance. This is particularly crucial to preserve the fighting force and regroup for future operations.

Advancing toward enemy positions, engaging in aerial combat, and reinforcing positions do not align with the definition of retrograde, which specifically involves a tactical withdrawal rather than engagement or reinforcement.
