What is the rear link count for the M1151 HMMWV?

• A. 2
• B. 4
• C. 5
• D. 3

Answer: (D)

In sling-load operations, how you rig the load matters for stability and control during flight. The rear link count refers to how many lifting links are used at the back of the M1151 HMMWV when it’s rigged for airlift. Using three rear links creates a triangulated rear attachment, which gives stable, balanced lift and helps prevent the vehicle from tilting or yawing as it rises or travels to the landing zone. Two rear links would lack that triangulation and could allow the rear to tilt or swing if there’s any slight mismatch in weight distribution or lift tension. Four or more rear links would complicate rigging and can lead to uneven tension or binding, making control more difficult for the pilot. Therefore, three rear links provide the appropriate balance of stability and manageable rigging for this setup.
