In the context of tactical missions, what does "retain" mean?

The term "retain" in a tactical mission context specifically indicates maintaining control over a terrain feature, ensuring it is not occupied or taken by enemy forces. This involves taking active measures to hold on to strategic positions, preventing the adversary from gaining access to that area.

In tactical operations, retaining a position is crucial for maintaining a defensive line or facilitating further movements. This can involve establishing and fortifying defensive measures, as well as engaging in reconnaissance to monitor enemy activities in the vicinity. The emphasis is on safeguarding that feature as a tactical asset.

The other answer choices describe different actions related to military operations but do not align with the specific definition of "retain." Securing an area against enemy attack encompasses broader defensive strategies, destroying threats focuses on offensive action, and supporting another force with direct fire pertains to cooperative maneuvers rather than the act of retaining control over a location.
