What is considered a capability within a UTC that commanders must deploy as a single entity?

A capability within a UTC (Unit Type Code) that commanders must deploy as a single entity refers to how certain functions or units are organized and managed for deployment purposes. The deployment echelon is the correct answer as it is an organizational element that commanders utilize to mobilize personnel and resources in a cohesive manner suited for operational deployment.

When a unit is designated for deployment, it must be equipped and ready to perform its specific mission without fragmentation. This ensures that all necessary components of the unit are together, functioning as a complete team. The deployment echelon specifically highlights the importance of maintaining the unit's integrity during the deployment process, thereby maximizing efficiency and effectiveness upon arrival at the operational theater.

Other aspects, such as registration, UTC development, or MAJCOM reporting, are essential components of logistics and deployment planning but do not inherently represent a cohesive operational capability that requires deployment as a single entity. Registration involves documenting and tracking personnel and equipment, UTC development pertains to the design and structuring of unit capabilities, and MAJCOM reporting relates to the chain of command's status updates and logistic assessments. However, none of these options encapsulate the operational necessity of deploying a complete capability as a unified unit, which is captured by the concept of the deployment echelon
