Which of the following is NOT an advantage of sling load operations?

• A. Use of multiple flight routes and landing sites to enhance sustainability and security of the ground unit.
• B. Establishment of multiple landing sites to support the maneuvering unit requirements.
• C. Greater movement flexibility for the ground commander to accomplish the tactical mission.
• D. Increases aircraft maintenance costs.

Answer: (D)

Sling load operations expand battlefield mobility by letting helicopters carry supplies and equipment to multiple spots, not tied to a single landing zone. Using several flight routes and landing sites helps keep the ground unit supported even if the primary site is compromised, boosting sustainability and security. Establishing multiple landing sites gives the maneuver element options to move and resupply where and when needed, improving overall maneuver capability. This approach also gives the ground commander greater latitude to reposition forces and adapt to the evolving situation, increasing tactical flexibility. The notion of higher aircraft maintenance costs is not a benefit of sling loads; it represents a potential burden rather than a gain, so it does not fit as an advantage.
