What are the four types of Rapid Runway Repair (RRR)?

The four types of Rapid Runway Repair (RRR) techniques are essential for maintaining operational airfields and ensuring that they can be used quickly after damage has occurred. The correct choice includes Folded Fiberglass Matting, AM2 Aluminum Matting, Cushed Stone, and Cretemobile, all of which are designed for rapid deployment and effectiveness in repairing damage on runways.

Folded Fiberglass Matting provides quick restoration of surfaces and is useful for light aircraft. AM2 Aluminum Matting is a robust option that allows for heavy aircraft operations and is easy to deploy. Cushed Stone is often used for filling in damaged areas to provide a stable surface temporarily. The Cretemobile is a mobile concrete mixing system that allows for an expedited way to create concrete patches directly on-site.

This combination of materials and techniques is optimized for speed and efficiency, ensuring that runway functionality can be restored swiftly in combat or emergency situations. The other options do not represent the standard practices or materials recognized for rapid runway repair, which is why they do not align with the correct answer.
