In Philippines, the Armed Forces of the Philippines (AFP) are responsible for territorial defense and assisting with internal security; much of the AFP's operational focus is on internal security alongside the Philippines National Police, particularly in the south, where several separatist insurgent, terrorist, and criminal groups operate and a considerable portion of the AFP is typically deployed; additional combat operations are conducted against the Communist People’s Party/New People’s Army, which is active mostly on Luzon, as well as the Visayas and areas of Mindanao; prior to a peace deal in 2014, the AFP fought a decades-long conflict against the Moro Islamic Liberation Front (MILF), a separatist organization based mostly on the island of Mindanao, which had up to 40,000 fighters under arms

maritime security is also a priority; the AFP's naval forces conduct naval interdiction missions in support of security operations on the southern islands, including joint maritime patrols with Indonesia and Malaysia; rising tensions with China over disputed waters and land features in the South China Sea since 2012 have spurred the AFP to place more emphasis on blue-water naval capabilities, including acquiring larger warships such as guided missile frigates, corvettes, offshore patrol vessels, and landing platform dock (LPD) amphibious assault ships

the Philippine military was formally organized during the American colonial period as the Philippine Army; they were established by the National Defense Act of 1935 and comprised of both Filipinos and Americans; the US and Philippines agreed to a mutual defense treaty in 1951; based on agreements signed in 2014 and 2023, the Philippine Government allows the rotational presence of US military forces, aircraft, and ships at up to nine bases in the Philippines; also in 2023, the US agreed to assist in modernizing Philippine defense capabilities, deepen interoperability, enhance bilateral planning and information-sharing, and combat transnational and nonconventional threats (2025)
