U.S. Marine Corps Lance Cpl. Jeremiah Smith, an Arizona native, an infantry Marine with 2nd Battalion, 5th Marine Regiment, 1st Marine Division, fires a M27 Infantry Automatic Rifle during Counter-small Unmanned Aerial System training as part of Service Level Training Exercise 4-26 at Training Area Prospect, Marine Corps Air Ground Combat Center, Twentynine Palms, California, July 17, 2026. With the debut of C-sUAS lanes at the Combat Center, Marines recognize and respond to unmanned aerial threats by employing emerging tactics, techniques, procedures, and maintaining a C-sUAS mindset in every operation, all while preserving the fundamentals that make rifle squads survivable and lethal. SLTE is a premier training event that ensures the Marine Corps remains a highly lethal, adaptable force capable of dominating the future multi-domain fight. (U.S. Marine Corps photo by Lance Cpl.
