Which of the following describes the theater army's design limitations?

The theater army's design limitations are accurately captured in the statement that it cannot function as the Joint Task Force (JTF), Joint Force Land Component Commander (JFLCC), or Army Forces (ARFOR) for major operations. This reflects its primary role and constraints within the larger operational framework of a joint operational environment.

The theater army is established to provide support and sustainment to forces rather than assume commanding roles in joint operations. By stating that it cannot operate in these capacities for major operations, it highlights the designed functions and limitations inherent to the theater army structure. Essentially, this emphasizes how the theater army functions within the joint operations framework, providing necessary support without leading major operational task forces.

Understanding this limitation is critical for military leadership and planning, as it informs how forces are organized and how operations are conducted on a larger scale, ensuring that appropriate components are designated for command responsibilities during multi-domain operations.
