Philippine representatives gather for a brief from Philippine Navy Cmdr. Reynan Carrido, chief of the cyber space division, for the first iteration of the Cyber Defense Exercise during Balikatan 23 at Camp Aguinaldo, Philippines, April 17, 2023. Balikatan 23, the 38th iteration of the annual bilateral exercise between the Armed Forces of the Philippines and the U.S. military, featured an inaugural joint, bilateral cyber defense exercise. Five teams of cyber defense experts defended a simulated military network, critical civilian infrastructure and other digital nodes from simulated malign actors such as criminal gangs, hacker collectives and a fictitious nation-state. Balikatan provides a venue to modernize the U.S. Philippine Defense Alliance, and improve collective capabilities and interoperability. (U.S. Marine Corps photo by Cpl. Fred Garcia)
