Final answer:
The concept of grouping Unit Type Codes (UTC) together is known as Deployment Integration, which organizes the flow of units for operational readiness.
Step-by-step explanation:
When Unit Type Codes (UTC) are collected or grouped together at locations in the United States or overseas, the concept being accomplished is known as Deployment Integration. This process ensures that units are systematically and efficiently integrated into the deployment flow, providing organized arrival of personnel, equipment, and supplies to a designated area of operations. The practice of deployment integration maximizes operational readiness and contributes to the successful accomplishment of a mission.
