(a) Installation property is that "station" property issued to a unit while
in a garrison or tenant status. It is turned in to the installation when the unit deploys.
Property authorized under TDA's and some CTA's is considered to be installation
(b) Organization property is that "mission essential" property that
enables a unit to operate. It deploys with the unit. Property authorized under MTOE's,
and some CTA's, is considered to be organizational property.
a. Prior to requisitioning any item of supply or equipment for a unit, there must
exist an authorization for the item, particularly equipment. It is incumbent upon supply
personnel to realize the value of authorization documents and the effect these
documents have on the validity of US Army requirements, the Army budget, and the
efficiency and operational readiness of the US Army. To produce organizations that are
properly balanced, the Army has established the Army Authorization Documents
b. The requirement/authorization documents include TOE, MTOE, TDA, and
common tables of allowances (CTA)
(1) The TOE document prescribes the mission, organizational structure, and
personnel and equipment requirements for a specific military unit. It provides a basic
guide or standard for the development of units on a worldwide basis. While TOE's
specify requirements, they do not authorize the equipment or personnel for particular
units. They must be viewed as documents that reflect the unit's requirements needed to
support the established doctrine and concept of the actual wartime mission.
(2) The MTOE document adapts the basic TOE mission capabilities,
organization, personnel, and equipment to the needs of a specific unit or type of unit.
The MTOE provides a major commander with the means to modify or adjust the
standard TOE for anyone or more of the TOE units within his command. While the TOE
specifies the requirements for units on a worldwide basis, the MTOE authorizes the
organization of a specific unit (or group of units) within an assigned command.
Therefore, two like units located in separate regions of the world will have somewhat
different MTOE's, but have an identical TOE.
(3) The TDA is another official authorization document. However, it is
different from an MTDE in that it is tailored to perform a specific support mission for
which no particular TOE exists. TDA units are basically non-deployable units organized
to fulfill mission, function, and workload obligations of a fixed support establishment in
CONUS or overseas (for example, medical activities and medical centers).
(4) The CTA document provides recommended allowances of common
items of equipment that are required worldwide: for example, clothing and equipment,
