U.S. Air Force Tech. Sgt. Joel Barriga, 163d Regional Training Site instructor, California Air National Guard, explains how to drive a pneumatic roller for Rapid Damage Repair during a weeklong course at March Air Reserve Base, Calif., May 19, 2026. Airmen learn to execute full-scale crater repair procedures, beginning with debris removal and upheaval marking before progressing through excavation, backfilling, compaction, and surface restoration. The RTS instructors measured both completion time and structural performance, conducting repair quality criteria testing to validate durability under projected aircraft loads.
