TWENTYNINE PALMS, CA, UNITED STATES 05.04.2019 - Sgt. Clinton W. Lehner, a weapons and tactics crew chief instructor with Marine Light Attack Helicopter Squadron (HMLA) 469, Marine Aircraft Group (MAG) 39, 3rd Marine Aircraft Wing (MAW), fires the M134 GAU-17 “Vulcan” cannon at targets during the Regimental Assault Course (RAC) at Marine Corps Air Ground Combat Center Twentynine Palms, Calif., May 4, 2019. The Marines conducted forward air controller airborne training combined with laser support and escort operations in support of the RAC during Integrated Training Exercise (ITX) 3-19. Integrating the MAW’s combat power and capabilities while supporting exercises and operations around the world generates readiness and lethality in our units. (U.S. Marine Corps photo by Lance Cpl.
