This chapter discusses the unique aspects of leader development, professional development and career management of Army National Guard (ARNG) and U.S. Army Reserve (USAR) officers. It also details how Army Reserve Component (RC) officers are affected by OPMS.

The Reserve Components of the Army include the ARNG and the USAR. When not in a Federalized status (under Federal control), the ARNG comes under control of the states, the territories of Guam and the Virgin Islands, the commonwealth Puerto Rico or the Dis­trict of Columbia. The USAR is a Federal force within the Depart­ment of the Army.

The ARNG and the USAR operate under separate and distinct systems according to specific laws and regulations. However, since the purpose of the RC is to augment the Active Component in times of need, it is imperative that the implementation of these laws and regulations allow for the seamless integration of RC units and indi­viduals into the Active force.

The RC consists of three categories: the Army Ready Reserve, the Standby Reserve, and the Retired Reserve. This chapter focuses on the Ready Reserve. The Ready Reserve is the largest category in the RC and contains the overwhelming majority of pretrained mili­tary manpower to augment the Active Component in time of war or national emergency. The Army Ready Reserve consists of the Army Selected Reserve, the Individual Ready Reserve (IRR) and the Inac­tive National Guard (ING).

(1) The Army Selected Reserve consists of the following:

(a) Units (USAR and ARNG). Soldiers assigned to USAR and ARNG units fall into this category, which is divided into two subgroups:

1. Drilling Unit Reservists. Soldiers assigned in drill status. These soldiers drill 48 Unit Training Assemblies (UTAs) per year and 14 days (15 days for ARNG) per year in annual training (AT) status.

2. Active Guard Reserve (AGR). Soldiers serving in an active duty status for at least 180 days, performing administrative and training duties in direct support of the ARNG and USAR. The primary objective of the AGR program is to improve the readiness of the Reserve Component.

(b) Training Pipeline (Non-deployable Account). Selected Re-serve enlisted soldiers who have not yet completed initial active duty for training (IADT), officers who are in training for profes­sional categories, or undergraduate flying training and cadets en-rolled in the Simultaneous Membership Program (SMP).

(c) Individual Mobilization Augmentation (IMA) (USAR only). Soldiers assigned to this control group perform at least 12 days of AT each year and are assigned to a specific duty position in an AC unit or organization.

(2) The Individual Ready Reserve (IRR) (USAR only) consists of the following:

(a) Control Group — Annual Training. Ready Reserve soldiers with a training obligation who do not belong to a USAR unit. They must perform AT when so directed.

(b) Control Group—Reinforcement. All other non-unit Ready Reserve soldiers not assigned to another control group.

(c) Control Group—Officer Active Duty Obligor. Active duty officers who are appointed in the USAR but do not enter onto active duty at the time of their appointment. These officers maintain their obligated status and may be ordered to active duty or duty with a ARNG or USAR unit.

(d) Control Group — Dual Component. Regular Army of the United States enlisted soldiers or warrant officers who hold Army Reserve commissions or warrants.

(3) Inactive National Guard (ING) personnel (ARNG only). Personnel in an inactive status in the Selected Reserve, attached to a specific National Guard unit. They muster once a year, but do not participate in training activities. ING soldiers are considered mobili­zation assets of the unit.
