The operation, codenamed Oplan Exodus, was intended to capture or kill wanted Malaysian terrorist and bomb-maker Zulkifli Abdhir and other Malaysian terrorists or high-ranking members of the Moro Islamic Liberation Front (MILF).

Mamasapano, officially the Municipality of Mamasapano, is a municipality in the province of Maguindanao del Sur, Philippines. According to the 2020 census, it had a population of 27,807.

The Moro Islamic Liberation Front is an Islamist group based in Mindanao, Philippines, which sought an autonomous region of the Moro people from the central government. The group has a presence in the Bangsamoro region of Mindanao, the Sulu Archipelago, Palawan, Basilan, and other neighbouring islands. The armed wing of the group was the Bangsamoro Islamic Armed Forces (BIAF), although the name of its parent organization, the MILF, was often used to refer to the BIAF.

The Bangsamoro Islamic Freedom Fighters (BIFF), also known as the Bangsamoro Islamic Freedom Movement, is an Islamist jihadist militant organization based in Mindanao, in the southern Philippines. It is a smaller player in the overall Moro insurgency and is mostly active in the Maguindanao provinces and other places in central Mindanao. It is a breakaway group from the Moro Islamic Liberation Front founded by Ameril Umbra Kato. Following Kato's death, the group split into three factions, one of which has aligned with the Islamic State, while the other two are less radical.
