Which advantage is associated with multiple LZs?

The advantage associated with multiple landing zones (LZs) is primarily the reduction in troop congestion. Having multiple LZs allows for an even spread of helicopters and troops, preventing a bottleneck situation where too many helicopters and personnel are trying to use a single LZ at the same time. This enhances the efficiency of operations, ensures that troops can be deployed quickly and safely, and minimizes the risk of accidents or delays caused by overcrowding.

Additionally, multiple LZs can help to obscure the exact location of troop deployments, further enhancing operational security by making it harder for adversaries to target specific locations for attacks. This strategic advantage becomes even more critical in high-stakes environments where time and space are closely linked to operational success.

When evaluating the other options, centralized resupply operations might be more efficient at a single point, while greater vulnerability to air attacks is not an advantage but a disadvantage that can arise from concentrating forces in one location. Facilitation of control can be improved with fewer LZs, which makes it easier to manage air traffic and landing sequences. However, maximizing the benefit of operations through reduced troop congestion is a key reason for employing multiple LZs.
