Trilateral Partnerships and Integrated Training
Brig. Gen. Vicente Blanco, Deputy Commandant of the Philippine Marine Corps, welcomed the participation of new partner nations in this year’s exercise. He emphasized that unity among allies sends a strong message of deterrence and regional solidarity.

Led by the Philippine Marine Corps and U.S. forces including Marine Rotational Force – Darwin 25.3 and the 3rd Marine Littoral Regiment, the training will span multiple Philippine locations. KAMANDAG 9 will also strengthen trilateral military coordination between the Philippines, Japan, and the United States.
