Regional Public Safety Battalion CALABARZON traces back its origin from the then 4th Regional Special Action Force (RSAF) Battalion which was activated in 1985, composed of two (2) PC Special Action Companies and one (1) INP Field Force Company.

Pursuant to RA 6975, otherwise known as the Department of the Interior and Local Government Act of 1990, Section 23 thereof mandates the establishment of the Philippine National Police (PNP) consisting mainly of personnel from the Integrated National Police (INP) pursuant to PD 765 and the officers and enlisted personnel of the defunct Philippine Constabulary (PC). This mandate of the newly-established Philippine National Police led to the renaming of the 4th RSAF Battalion to 4th Regional Mobile Force (RMF) during the last quarter of 1996. Meanwhile, the effort to “civilianize” the terminologies of the PNP took effect and the 4th RMF was renamed as the 4th Regional Mobile Group.

On September 1, 2002, pursuant to Executive Order Nr. 103, Series of 2002, the Administrative Region was divided into Region 4A (CALABARZON) and Region 4B (MIMAROPA). In order to realize the intent of the said executive order, the DPL-NHQ, PNP issued General Order Nr. 02-10 on August 18, 2002, effectively deactivating PRO 4 to give way to the activation of PRO 4A (CALABARZON) and PRO 4B (MIMAROPA). The 4th Regional Mobile Group was renamed as Regional
