The Battle of Camp Abubakar, codenamed Operation Terminal Velocity,[1] was the final phase of the 2000 Philippine campaign against the Moro Islamic Liberation Front which resulted in the capture of Camp Abubakar al Siddique, stronghold of the Moro Islamic Liberation Front and its largest settlement, and seat of its Shariah-based government.

[3] Camp Abubakar covered approximately forty square miles and included a mosque, a madrasah, commercial and residential areas, a weapons factory, a solar energy system, and segments of seven different villages.

At the same time, the Muslim rebels began attacking Philippine Army units in Buldon, Maguindanao, in what proved to be the initial salvo of hostilities in locations leading towards Camp Abubakar.

At one point during the battle, three Northrop F-5's of the Philippine Air Force dropped 750 lb bombs on Camp Abubakar, targeting communications facilities.

[1] By July 8, 2000, the government forces had captured among others, the headquarters of the Bangsamoro Islamic Women Auxiliary Brigade, the headquarters of the 2nd Battalion, GHQ Division of the BIAF, the Supply and Logistics Office of the HQs National Guard Division of the BIAF, the MILF Abdurahaman Bedis Memorial Military Academy, and MILF chairman Salamat Hashim's personal quarters.

[8] The next day, then-President Joseph Estrada himself visited the captured Muslim rebel camp and raised the Philippine flag there, "in assertion of sovereignty".

He also brought truckloads of lechon and beer for the government troops, earning criticism from both devout Muslims and Catholic clerics for his insensitivity.
