operation, although the main effort may change as the situation

interfering with a particular operation.
Occupy: Moving a friendly force into an area without opposition
so it can remain in the area and retain control of that area.
Penetrate: An offensive maneuver where an attacking force seeks to
rupture enemy defenses on a narrow front and disrupts the defensive
system.
Relief in place: By the direction of a higher authority, a tactical
enabling operation where all or part of a unit is replaced in an area by
the incoming unit.
Retain: A tactical mission task to occupy and hold a terrain feature to
ensure it remains free of enemy occupation or use.
Retirement : A directed, rearward movement by a force that is not in
contact or does not anticipate contact with the enemy. A form of
retrograde where a force (out of contact with the enemy) moves away
from the enemy.
Screen: Security operations that maintain surveillance and primarily
provide early warning to the protected force without decisively
engaging the enemy.
Secure: An action that prevents a unit, facility, or geographical
location from being damaged or destroyed by enemy action.
Security operations: Actions a commander undertakes to provide
early and accurate warning of enemy operations and provide the
protective force, time, and maneuvering space to react to the enemy.
