The 15th Infantry Division (Ready Reserve), Philippine Army, known as the Defender & Builder Division, is one of the Army Reserve Command's ready reserve infantry divisions.

The unit specializes in Urban Warfare, Urban Search and Rescue, Humanitarian Assistance and Disaster Relief, and Civil-Military Operations. It operates in the National Capital Region.

The Philippine Army felt the need to re-organize its reserve units in the National Capital Region (NCR) when the 9th Infantry Division (Ready Reserve) was deactivated and the newly created regular infantry division (9ID) took its numerical designation.

On 16 June 2006, pursuant to the directives of the Commanding General of the Philippine Army, the Army Adjutant General published General Orders number 290. The order tasked the Philippine Army Reserve Command to activate a Reserve Infantry Division to fill in the vacant post of the former 9ID(RR).

Finally on 20 July 2006, with further consultation from his staff, Brigadier General Emmanuel Cayton AFP, then Commander; Army Reserve Command transferred operational and administrative control of the 15th Infantry Division (Ready Reserve) under the NCRRCDG pursuant to General Orders Nr. 233 and Colonel Marcelo B Javier Jr INF (GSC) RES PA was installed as its first commanding officer.

The 15th Infantry Division (Ready Reserve), then was composed of line task units re-organized from the deactivated 9th Infantry Division (Ready Reserve) PA. Additional units were later added as the division grew to full strength.

The Commission on Appointments, confirms the promotion of Colonel Javier Jr to Brigadier General on 21 September 2012.
