Unified in Strength: Allied Forces Execute Archipelagic Defense Masterstroke in KAMANDAG 9

Wazzup Pilipinas!?

MANILA, Philippines — In a powerful exhibition of allied precision, resolve, and unity, the United States, the Philippines, Japan, and South Korea converged under Exercise KAMANDAG 9 to demonstrate an unprecedented level of multi-domain operational dominance—firmly reinforcing the Philippine Archipelagic Coastal Defense Concept.

At the heart of this landmark operation was the Marine Rotational Force – Darwin (MRF-D) 25.3, forward deployed under I Marine Expeditionary Force (MEF) Forward, which spearheaded a strategic Combined Joint All-Domain Operation (CJADO) from June 1, 2025. This wasn’t just an exercise. It was a resounding message to the world: the Indo-Pacific's key allies are ready, synchronized, and capable of defending critical maritime terrain across one of the world’s most strategic and contested regions.

Constructive Kills, Real-World Readiness

At the core of the CJADO were multi-phased “constructive kill” (CK) operations—simulated strikes vectored at notional targets but executed with the precision, coordination, and timing of real-world warfare. Stretching across hundreds of nautical miles, this exercise integrated joint forces from the Philippines, United States, Japan, and South Korea. It tested and validated advanced capabilities in precision fires, maritime maneuver, intelligence, cyber defense, and distributed command and control — the very foundation of modern warfighting.

“This is what combined operations looks like at the highest level — forward-postured, allied-enabled, and terrain-informed,” declared Col. Jason C. Armas, commanding officer of MRF-D 25.3 MAGTF. “This was more than a simulated strike. It was a deliberate act of maritime integration and dominance. We proved that our Marine Corps can maneuver at scale, with precision, and in lockstep with our partners.”

Multi-Nation Coordination Across the Archipelago

From the strategic islands of Batanes to the coastal bastions of Palawan, allied forces coordinated a symphony of simulated precision strikes. The 3rd Marine Littoral Regiment (MLR) employed the cutting-edge Navy Marine Expeditionary Ship Interdiction System (NMESIS), targeting notional maritime threats to support Philippine Marine forces in the north. Meanwhile, in the south, MRF-D coordinated with the U.S. Army’s 1st Multi-Domain Task Force (MDTF) to launch long-range simulated strikes, clearing maneuver corridors and neutralizing mock adversaries west of Palawan and north of Luzon.

The operation culminated in the strategic insertion of a combined U.S.-Philippine rifle company near Berong, Palawan. This included Philippine Marine Brigade Landing Teams and soldiers from Japan’s Amphibious Rapid Deployment Brigade (ARDB), who executed a bilateral ship-to-shore movement via Combat Rubber Raiding Crafts (CRRC). Simulating a humanitarian disaster response, the troops immediately transitioned to casualty identification, triage, and evacuation to Japanese and U.S. medical facilities.

Full Kill Chain: From Strike to Defense

Following successful strikes and insertions, allied forces fortified Berong’s coastal defenses in anticipation of simulated enemy amphibious landings. The exercise climaxed days later with a live-fire counter-landing operation near Quezon, Palawan—an explosive finale showcasing the full kill chain: sensing, striking, maneuvering, and defending.

“This training under KAMANDAG's constructive kill framework sharpens situational awareness and accelerates target acquisition in support of maritime denial operations,” emphasized Maj. Sivel Sarmiento, operations officer with the Philippine Marine Corps.

The Unseen Edge: Cyber, Intelligence, and Coordination

Behind every successful maneuver and strike was a complex web of cyber defense, intelligence gathering, and real-time communication. Joint ISR (Intelligence, Surveillance, and Reconnaissance) assets—including unmanned aerial systems and maritime surveillance platforms—relayed vital target data. Defensive cyber teams, like the MRF-D’s DCO-IDM unit, ensured that no adversary could disrupt operations.

“The DCO-IDM team ensured uninterrupted execution of critical events,” said 1st Lt. Jared Haynie, officer in charge of cyber defense. “We were not just defenders—we were enablers of every successful mission thread.”

All efforts were centralized at the Fires and Effects Coordination Center (FECC), which served as the strategic hub connecting Philippine and U.S. command centers across more than 1,000 kilometers of archipelagic terrain. Coordinating with the Philippine Navy and Coast Guard, the FECC ensured the seamless integration of naval and land forces into a shared maritime awareness network.

Defending the Homeland, Strengthening the Alliance

KAMANDAG 9 was more than a military drill. It was a compelling affirmation of the enduring partnership between the Philippines and its allies—built on shared values, mutual defense, and regional stability. Through the Philippine Archipelagic Coastal Defense Concept, the nation is reasserting its sovereign rights, securing its seas, and demonstrating its pivotal role in the Indo-Pacific’s security architecture.

“This CJADO proves that deterrence is not abstract,” Col. Armas concluded. “It’s observable. It’s measurable. And it’s executable in terrain that matters—alongside allies who can see, decide, and act faster than any adversary. This wasn’t a rehearsal. It was a declaration of readiness, unity, and unwavering resolve.”

A Future-Proof Strategy

As the waves settle and the echoes of simulated firepower fade, one truth becomes clear: the Philippines and its allies are not just watching history unfold in the Indo-Pacific—they are shaping it. And with every exercise like KAMANDAG 9, they reaffirm a collective commitment to peace, security, and freedom across the vast and vital seas of Asia.
