What statement best describes the difference between a primary LZ and an alternate LZ in planning?

• A. Primary is the preferred choice based on optimal conditions; alternate is the backup ready if conditions prevent using the primary.
• B. Primary is only for emergency evacuations; alternate is for routine moves;
• C. Alternate is always closer to the unit than the primary;
• D. Primary and alternate are interchangeable without conditions.

Answer: (A)

In LZ/PZ planning, you pick a primary LZ as the preferred landing zone based on the best conditions and most favorable access for the operation. The alternate LZ is a backup location you reserve to use if factors such as weather, surface conditions, obstacles, or security make the primary unusable. This arrangement keeps the mission on track by providing a ready-to-go option if the situation changes.

That’s why this statement fits best: the primary is the preferred choice under optimal conditions, and the alternate is there as a ready backup when those conditions aren’t met. It isn’t about emergencies alone, nor about distance differences or interchangeable use without criteria. The other options miss the point by suggesting the primary is only for emergencies, that alternates are always closer, or that they can be swapped without any conditions.
