Individual Mobilization Augmentee (IMA) Soldiers have shown to be an integral part of our modern day force.

The overall objective of the IMA program is to facilitate the rapid expansion of the Active Army wartime structure of the department of Defense and/or other departments or agencies of the U.S. Government to meet military manpower requirements in the event of military contingency, pre-mobilization, mobilization, sustainment, and/or demobilization operations.

IMA Soldiers participate in a large number of CO-ADOS, ADOS, and mobilization tours to support various commands and area of operation.

The IMA program is comprised of 79 authorized agencies. The assigned Soldiers to these agencies have special planning and support requirements to which the handbook will help the Soldier, the agency coordinator, and the HRC DIMA Management Team function more efficiently.

The IMA handbook covers the most frequently addressed issues within the program. Please take the time to review the handbook in detail to help your understanding of the IMA program: Individual Mobilization Augmentee (IMA) Handbook

 Are all IMA Soldiers part of the Selected Reserve (SELRES)?
Per AR 140-10, Chapter 2-4a The Selected Reserve consists of Soldiers assigned to (2): Control Group (Individual Mobilization Augmentee) under the administrative jurisdiction of commander, HRC. Soldiers assigned to this control group are serving in specified duty positions as IMAs, per AR 140-145.

 What is the difference between an IMA and DIMA?
The terminology DIMA has been changed to be only IMA. The distinction is general officers are not authorized IDT for pay unless they are in a "duel hat" position.

 Who publishes AT orders for IMA Soldiers?
Using the Automated Orders Resource System (AORs) the IMA Agency Coordinator initiates the request for orders and then it is published by HRC.

Soldiers should complete the DA 2446 (.pdf) (.xfdl) and submit to their IMA Agency Coordinator for processing. Click here for an example DA Form 2446. AORS or manual DA FM 2446 are to be received as early as 90 days prior to start date and never less than 30 days to start date. Health Service professionals who require credentialing must have their request for AT submitted not less than 45 days to start date.


Visit Army Human Resources Command's website for more information on the Individual Ready Reserve program:

The Army Human Resources Command (HRC), Fort Knox, manages the Army Reserve's IMA Program and its more than 4,000 officer, enlisted, and warrant officer positions around the world. Proponent agencies provide HRC with AOC/MOS requirements for vacancies, and HRC appropriately realigns/reassigns Soldiers to meet those requirements.

With the Army's draw-down, Army Reserve IMA Soldiers are critically needed to fulfill proponent agency wartime structures. HRC IMA program managers are increasing their marketing activities to promote awareness of the IMA program and capture skilled Soldiers leaving the Active Army, Army Reserve or National Guard.
