LP/OP stands for?

• A. Listening Post/Observation Post
• B. Landing Post/Operational Post
• C. Local Post/Observation Post
• D. Listening Point/Observation Post

Answer: (A)

In infantry operations, LP/OP stands for Listening Post/Observation Post. These forward positions are set to provide early warning and information about enemy movements. A Listening Post focuses on sound and signs of activity, often staying low and quiet while listening for footsteps, voices, or vehicle noises, then relaying what’s detected. An Observation Post sits in a vantage point with clear sight lines to observe enemy dispositions and movements, reporting what is seen and sometimes guiding fire or maneuver. Together, they give the unit time to react—whether to improvise a defense, adjust routes, or call for supporting fire—before a direct engagement. The other options don’t match the established Marine Corps terminology, which is why this pairing is the correct one.
