Kamandag stands for "Cooperation of Warriors of the Sea" and is aimed at increasing counterterrorism, humanitarian assistance and disaster-response capabilities through bilateral military exchanges between the Armed Forces of the Philippines (AFP) and US forces, the statement said.
Washington and Manila have long been conducting joint military activities to strengthen interoperability and boost the overall combined responsiveness of their forces to crises in the Indo-Asia-Pacific region.
"The exercise will… further reinforce our illustrious decades-long alliance," Molly Koscina, a spokeswoman for the US Embassy in Manila, said in the statement.
This year's Kamandag replaces Phiblex, an annual US-Philippines bilateral exercise that combined amphibious-landing capabilities and live-fire training with humanitarian civic assistance efforts. The last Phiblex took place in October 2016 before the exercises were canceled by Philippines President Rodrigo Duterte.
Since Duterte took office in June 2016, there have been some changes in the existing range of US-Philippines military exercises, with some cancellations, additions, refocusing and renaming.
Kamandag maneuvers will be held at multiple training areas and bases on the Philippine main island of Luzon and involve a total of 900 Marines and sailors.
Servicemembers will practice combat lifesaving, shipboard mass casualty response, live-fire training, urban operations, movement ashore and humanitarian assistance and disaster response. The exercise will run until October 11.
