Which HLZ requirement addresses the relation between combat power and need for additional LZ or separation between waves?

• A. Ground commander's concepts of operations
• B. Free of obstacles
• C. Size determines combat power and need for additional LZ or separation between waves
• D. Identifiable from the air

Answer: (C)

The key idea is that the landing zone size is tied directly to how much combat power you plan to insert and how you’ll manage that flow. If you’re bringing in a large force with vehicles and equipment, you’ll need a bigger HLZ to accommodate the number of aircraft simultaneously and to unload efficiently. That bigger size may also mean you need additional LZs or you’ll split the lift into multiple waves with spacing between them to avoid bottlenecks, reduce exposure to enemy fire, and maintain safe, orderly arrivals. So, saying that the size determines combat power and the need for additional LZs or separation between waves captures how planning the HLZ footprint drives both capacity and sequencing.

Other HLZ criteria focus on safety and markings—being free of obstacles and identifiable from the air—but they don’t address the relationship between how large the HLZ is and how much force you’re inserting or how you split waves.
