Which of the following are the three phases of PZ/LZ Operations?

• A. Recon; Insertion; Extraction
• B. Selection; Marking; Controlling
• C. Preplanning; Marking; Extraction
• D. Planning; Insertion; Extraction

Answer: (B)

The three parts of PZ/LZ operations are selecting the landing site, marking it, and controlling the operation.

Selecting the site means evaluating terrain, obstacles, wind, enemy presence, and approach/departure routes to choose a location that provides safe access for aircraft and quick egress for landing units. It’s about finding a spot that minimizes risk and fits the mission’s spatial constraints.

Marking the site gives pilots a clear reference from the air. You use standardized ground signals, colors, panels, lights, or smoke to define the LZ/PZ boundaries and layout, ensuring aircraft can accurately land even in reduced visibility or at night. Marking communicates where to land and where not to land, and helps prevent confusion with nearby zones.

Controlling the operation involves managing the aircraft and ground movement once the landing begins. This includes coordinating with pilots, maintaining security around the zone, deconflicting air and ground traffic, issuing signals or commands, and adapting to changing conditions such as enemy activity, weather, or unforeseen obstacles.

The other options describe broader mission steps or less specific sequences, but they don’t capture the distinct three-part process of selecting, marking, and controlling a PZ/LZ.
