1st Regional Community Defense Group

The 1st Regional Community Defense Group, Army Reserve Command is a line unit of the Army Reserve Command of the Philippine Army. It was created for the sole purpose of Reserve Force management, procurement, and organisation in the areas encompassing Northern and Central Luzon.

Training
Training is the major task handled by the 1st Regional Community Defense Group. Its primary arms are the university/college-based Department of Military Science and Tactics-administered mandatory basic and the optional advanced Reserve Officer Training Corps; and the territorial unit-administered Basic Citizen's Military Training.

Basic Reserve Officer Training Corps and Basic Citizen's Military Training graduates are enlisted as privates in the Reserve Force, while advanced Reserve Officer Training Corps graduates are enlisted as sergeants. Completion of Advanced Reserve Officer Training Corps is considered a graduate qualification in military science, and such graduates who subsequently progress to the Probationary Officer Training Course are commissioned as second lieutenants.

Other than time-in-grade and merit promotions, rank adjustments are authorized depending on civilian qualifications, as well as their reciprocity to the operating environment.

Types of reservists
There are currently two types of reservists in the Armed Forces of the Philippines Reserve Force:
 * Ready Reservists: physically-fit and tactically-current reservist personnel that are always on constant alert and training; ready to mobilise once a mobilisation order has been given.
 * Standby Reservists: reservist personnel who do not maintain currency in specialization qualifications but the base for expansion, support and augmentation to the Ready Reserve Force as needed.

Units
The 1st Regional Community Defense Group has several line units under its command, making the administration and training of reservists more compartmentalized and territorial based.
