Reserve Components of the Army Dental Corps:

The United States Army is made up of three components: Compo 1—the Regular Army; and two Reserve
components—Compo 2: the Army National Guard and Compo 3: the Army Reserve. Both reserve components
are primarily composed of part-time soldiers who train minimally once a month, known as Battle Assembly,
Unit Training Assemblies (UTAs), or simply “drills”, while typically conducting two to three weeks of annual
training each year. Both the Regular Army and the Army Reserve are organized under Title 10 of the United
States Code. The National Guard is organized under Title 32. While the Army National Guard is organized,
trained and equipped as a component of the U.S. Army, individual units are under the command of individual
state’s governors. However, units of the National Guard can be federalized by presidential order and against the
governor’s wishes.

COMPO 1 is the Active Duty component and consists of MTOE (Modified Table Of Organization &
Equipment) units that are trained as combat service support units. Each TOE is identified by a unique number
that should remain the same throughout the life of the organization. TOE developers, in coordination with the
TRADOC force designers, are responsible for developing the proposed TOE number for deployment. Simply
put, MTOE units are operational forces; and TDA (Table of Distribution and Allowances) are typically CONUS
and fixed facility units that support the MTOE units with an organizational structure, personnel, equipment
requirement, and authorizations of a military unit to perform a specific mission for which there is no appropriate

COMPO 2 & 3. If you are leaving active duty in the REFRAD category, you should consider the option of
continuing your military service in the National Guard or US Army Reserves. Among the many advantages for
continued service are the following: Continued camaraderie and interaction with selfless service colleagues;
Continuation of retirement points toward a substantial military retirement; Continued participation in minimal
cost Health Insurance – Tricare with Humana Military for your families; Low Cost Life Insurance; Continuation
of active recognition benefits for traveling in a Preferred Status; PX and Commissary Privileges; and Optional
deployments and humanitarian missions to name a few.

COMPO 2 is comprised of the US National Guard units which are MTOE units under state control but can be
federalized. There are allocated Dental Corps Officer positions per state.

COMPO 3 is comprised of the US Army Reserve which include several different types of positions…. MTOE
(SELRES Reservists in Operational, Forward Deploying units), TDA (SELRES Reservists at Fixed Facility,
Typically CONUS, MTOE Support), DIMA/IMA (SELRES Reservists with alignment to Active Duty positions
as PROFIS to their counterparts), APMC/old NAAD (TPU model Reservist with inability to attend unit Battle
Assemblies within 100 miles/3 hour drive), and IRR (Non-SELRES Reservists in Transition, Standby, NonPaid, No Points).
