Required capabilities and attributes are identified by which of the following?

The identification of required capabilities and attributes is primarily associated with Joint Functional Concepts. These concepts delineate how joint forces plan and execute operations across a range of military activities and scenarios. They serve as a foundational framework for understanding the capabilities needed to meet future operational challenges and how these capabilities can be integrated effectively within a joint environment.

By focusing on capabilities, Joint Functional Concepts provide a comprehensive view of the attributes necessary for successful mission accomplishment across various domains, such as air, land, maritime, cyber, and space. This understanding helps military planners and strategists ensure that forces are adequately equipped and prepared to respond to diverse threats in an evolving strategic landscape.

In contrast, Strategic Concepts provide overarching guidance on military strategy but do not specifically break down the required capabilities. Operational Plans detail how resources will be allocated to achieve specific objectives but are not primarily focused on outlining the inherent capabilities needed. Tactical Guidelines provide instructions on how to execute specific tasks or missions but do not encompass the broader view of required capabilities and attributes. This is why Joint Functional Concepts is the correct choice, as it directly addresses the identification of capabilities and attributes essential for effective military operations.
