Two government command groups were immediately dispatched after reports of the occupation of Oakwood, and of movement of the Marine contingent from Ternate towards Camp Aguinaldo were confirmed. The Crisis Management Staff was formed at the Command Operation Center in Camp Crame, and the Advanced Command Post of the PNP was established behind the Intercontinental Hotel in Makati. Marines and Army officers later joined the PNP at the Makati post, and the Southern Police District Director, Police Chief Superintendent Jose Gutierrez, was designated as the ground commander. At around 2:00 am on July 27, Abu was informed by the Joint Operation Center in Camp Aguinaldo about the presence of troops moving towards Metro Manila. Most of these troops were coming from Ternate, Cavite. At this time, the Marines under Teodosio were already poised to stop the troops. They were pre-positioned around the car park behind Oakwood.
