Which of the following is NOT an advantage of lane training?

The identification of the option regarding requiring extensive resources as not being an advantage of lane training is accurate. Lane training is designed to be efficient and effective, allowing units to conduct realistic and relevant training without needing large amounts of equipment or vast areas of land.

This method usually capitalizes on the use of limited but well-defined training areas, thus minimizing the resources typically required for larger training exercises. The environment is unit-controlled, allowing for tailored training objectives that can be adjusted based on the unit's specific needs. Tasks are created based on these objectives, ensuring that training remains focused and relevant.

In contrast, the aspect of requiring extensive resources would detract from the benefits lane training offers, making it a disadvantage rather than an advantage. Thus, recognizing that requirement for extensive resources is not an advantage of lane training is crucial for understanding its practical application in military training scenarios.
