Which is not a benefit of sling load operations?

Sling load operations offer several benefits that enhance logistical capabilities, especially in challenging terrains or situations where traditional ground transport is hindered. Among these benefits are the versatility in accessing hard-to-reach locations, the speed of delivery that circumvents typical ground delays, and a significant reduction in the need for extensive ground transportation.

The statement regarding sling load operations being "only for transporting light cargo" is not true, which makes it the correct choice in this context. Sling load techniques are adaptable and can be used to lift various types of cargo, including heavier items, provided that the aircraft's lifting capacity and the appropriate rigging are applied. This flexibility allows for a broad range of operational uses beyond simply moving lightweight supplies, making the capability more valuable in diverse military operations.
