What This Field Means
Organizations or personnel formally assigned to the unit even though they may not be organic to its standard structure.
This describes organizations or personnel formally assigned to the unit beyond its inherent organic structure. It explains enduring additions that can change what the unit contains without redefining its basic type.
How to Read It Correctly
Assigned composition is not organic composition and not a temporary attachment. Assignment normally reflects a formal relationship; physical presence or cooperation alone is not enough.
Example
A unit formally assigned to a command for an established period.
Technical Specification
The database column is [USMIL-Unit].[Unit].[AssignedComposition]. Optional evidence-derived assigned-force narrative. Assignment must be distinguished from attachment and organic membership.
Identify the assigned elements and the applicable period or authority when evidence supplies it. Keep exact, effective-dated relationships in the relationship model and use this field as a readable summary.

Allowed Values and Definitions
No preset menu applies to this field. It stores an identifier, relationship, measurement, date, timestamp, or evidence-derived narrative. Valid content is governed by the SQL type, key relationship, nullability, retained evidence, and the field-specific recording rule above. A list of observed contents would be data, not a list of allowed options.
Missing, Unknown, and Conflicting Information
A database NULL is permitted and means that no value is presently stored. It does not prove that the fact never existed, that the answer is no, or that the concept does not apply. Missing information must remain visibly different from a supported negative or inapplicable conclusion.
Connections to Other Fields
- Organic Composition — The people or subordinate organizations that belong to the unit by its normal design rather than by a temporary assignment.
- Attached Composition — Organizations temporarily placed with the unit for support, control, or a particular mission.
- Assignment Status — How the unit is connected to another command—assigned, allocated, attached, supporting, or supported.
- Administrative Command — The service-side organization responsible for administration, readiness, personnel, training, and support.
- Operational Context — The operation, campaign, exercise, contingency, or standing plan in which a command relationship or unit activity applies.
