Jacqueline Akamelu January 29, 2026 at 04:59PM Semper Durus is an annual interagency training exercise designed to strengthen regional defense, test anti-terrorism measures, and ensure personnel safety against evolving threats across Marine Corps Base Camp Pendleton. Before, during, and after Semper Durus, agencies aboard the installation maintain readiness and response effectiveness through targeted training exercises focused on specific areas. With the focus on response effectiveness, partnering agencies across the installation participated in Command Post Exercise II at MCB Camp Pendleton, California, Jan. 28, 2026. The intent of CPX II was to combine the efforts of various agencies across Marine Corps Installations West to exercise staff actions in response to a simulated contamination of the installation’s food supply. This included verifying the safety and security of food sources and their delivery, identifying the impact of food delivery interruptions, determining required response actions to re-establish safe food distribution, and exercising the Camp Pendleton Fire Department’s hazardous materials response procedures.
